I am new to Laravel. When I am in debug mode I get the following errors every time every page loads:
The payload is invalid
After pressing two times on Continue I get the error
The MAC is invalid
The error messages are located inside the encrypter.php file. After pressing "Continue" again, I can proceed with debugging with breakpoints and so on, and everything works fine. The $payload-variable is null.
The project is still very basic. Only some things like CRUD like explained on tutorials.
What is payload? And am I missing some kind of configuration? How to get rid of these error messages?
The answer is found in this post:
Can't using Visual Code to debug in Laravel project
I also:
closed VS Code Editor
cleared all history in my browser, including cookies and cache
ran the commands as mentioned in the post inside the windows cmd window (so not the integrated terminal inside VS Code Editor)

I am working in an ember application. The version is "ember-cli": "1.13.13".
For a very strange reason, debugger doesn't work in Chrome. (I also tried Safari, and Firefox developer's edition. Same thing.)
Specifically, the problem is I put a debugger statement in a function. Ember app loads and hits the function and the debugger statement in the function. What happens in the Developer Tools -> Sources tab is that it doesn't show me the function that the debugger is in.
Instead it keeps highlighting the last line of app-boot.js file. The breakpoint, or the line that it's paused on, is not showing up at all. (see screenshot attached)
Furthermore when I step into the function call using the down arrow, it remains at app-boot.js, so I have no idea whether it did step into the function or not.
This has been plaguing me for a while now.
I've resolved many times similar error on OSX + Chrome by using Empty Cache and Hard Reload - after that code in Sources tab was updated and I could correctly see actual source code.
Make sure you didn't blackbox scripts of your application.
Alternatively you could try to reinstall npm packages, bower packages - it might be issue with creating source maps in Ember CLI.
If nothing helps please investigate your JavaScript and associated map files and check if something might be missing, or maps don't update. You could possibly try turning them on and off in Ember CLI.
See Source Maps section in Ember CLI guides how to enable/disable them.
I'm currently (trying) to develop an app with Worklight Studio 5.0.6 and Dojo (Mobile) 1.8.3. I have a really hard time to to find a proper method for debugging. After waiting 5-10 minutes for the build an deploy-process on the server, an error usually looks like this in the Chrome debugger:
How am I supposed to track down this error in MY source? The whole stack trace consists entirely of Dojo code which generates an absolutely useless error message after 20 abstraction layers.
Seriously, how do you guys handle this in real life? What methods do you use for debugging Dojo-driven apps in the browser?
spyro
For dojo.parse errors, I find it useful to pause the Chrome debugger on all exceptions (the purple icon on your screenshot, should be blue). You usally get more details about the cause of the error, the name of the DOM node being parsed, etc. in the first exception being raised.
Rémi.
Debugging dojo based application should be the same as debugging any javascript application.
Usually I will follow these steps:
add console.log() somewhere in code: this is fast and most of time this is enough.
set breakpoint in debugger: if step 1 is not enough, you can base on error information to set breakpoint before error line, then step in or step out.
comment out recently changes: for some error which is hard to find the error line, for example, parse error in your case, the good way is comment out your recently changes one by one till back to your last working version. Or, return to your last working version, then add code back one by one.
Create a simple application to reproduce the error : if your application is very complicate and it is hard for you to follow above methods, you can try to create a new application which mimics your current application but with simple logics and try to reproduce the error.
Based on experience : Some errors, for example, extra ',' in the end of array which works at chrome and firefox, will report a nonsense error information at IE. Debug these kinds of errors is very difficult, you can base on your experience or do a google search.
Did you provide isDebug: true in your dojoConfig? Also, try to see if the same occurs in other browsers.
Update: I recently discovered that there are issues with Google Chrome and Dojo debugging and I think it has to do with the asynchronous loading of files. As you can see in the provided screenshot of #spyro, the ReferenceError object is blank (which you can notice because of the empty brackets {}). If you want to solve that, reopen the console of Google Chrome, (for example by tapping F12 twice). After reopening the ReferenceError should not be empty anymore and now you can expand that object by using the arrow next to it and get a more detailed message about what failed.
Usually what I do in situations like that is to place a breakpoint inside the error callback (line 3398 in your case) and then look into the error variable ("e").
I am not sure how familiar you are with the Web Inspector, but once you hit the breakpoint open the Web Inspector 'console' and check for the error properties "e.message" and "e.stack" (just type in "e.message " in the console).
Also, during development it is better to avoid Dojo optimization / minification, which greatly improve your debug-ability.
Bottom line is to try to place the breakpoint before the error is thrown.
n00b here. After searching the forums I have not yet come across this problem as I am experiencing it.
I have a CI site that was working correctly until about three days ago. My problem is as follows:
On button click - Page Loads correctly.
On Enter press - CI Blank Page of Death loads.
For example: When I login, after the login process has run it must reroute me to the Dashboard, unless I still have a temporary password where I get rerouted to the "Change Password" screen first and then to the Dashboard.
AS LONG AS I USE THE BUTTONS AND CLICK THEM EVERYTHING WORKS.
On ENTER PRESS, I get the Blank Screen of Death.
However, on TAB to BUTTON and then ENTER it works.
The problem is not consistent however. I have some processes that do not have views attached and NONE of them will run - hit ENTER and get blank. They are all failing on ENTER PRESS.
I am slowly going off my trolley. Logging is ON, Directories for cache and logs are 775. NOTHING is showing in my logs...
First Try to active error handlers for displaying of errors for addittional info to post here what error is occuring..
// change settings for error handler to show errors
// $this setup is used for checking errors for development to be shown....
ini_set('display_errors', 1);
error_reporting(E_ALL);
by the way if your using CI version 2 higher
you can see it in its index.php file an configuration for displaying error also.
define('ENVIRONMENT', 'development'); //just set up environtment to development
Even though there are accepted answers I wanted to add a way that worked for me to figure out this problem.
Usually the "Blank Page" indicates a PHP parsing error somewhere in the code. Strange thing for me was that on my local MAMP based test server the code ran fine. I FTP it to my hosted server and all of a sudden, blank page of death.
Even though I had errors on, log errors on, display errors on, nothing appears in any log file.
I was able to find the error by a funny little trick. I added an echo line in CodeIgniter.php in the system/core. Obviously hacking the core was not a great idea but all I wanted to do was to see how far it was getting in the load process.
When my echo appeared after trying to load a page on the remote hosted server it also displayed the parsing problem in a derived controller! Not sure why the error did not come out without the "echo" added. But adding it seemed to trigger some output to be generated, IE my echo line and the PHP parse error was appended.
Not sure if this will help anyone but it turned out to be a nice easy way to find the error which only showed on the remote server.
Obviously, don't forget to put your core file back to its original state without the echo.
This was fixed by copying the application into a fresh CI 2.3 install.
I have no idea what actually caused this "erratic" behaviour.
The application worked correctly as designed whenever a BUTTON was CLICKED but gave the blank death screen when ENTER was PRESSED.
This inconsistent behaviour is what threw me. The fact that my logs (CI and APACHE) also showed nothing was also very strange. Had this been a parse error, surely the behaviour on "Click" and on "Enter Press" should have been the same.
My non-view controllers for various ad-hoc admin jobs are now also working correctly, which they were not before, as they use "Enter Press" (having no buttons to "Click").
I am still going to invite best guesses as to why this behaviour occurred the way it did.
Surely someone out there (Phil Sturgeon et al) with extensive CI experience has encountered this non-consistent blank screen behaviour and knows what caused it.
Thank you to all the people who took the time and effort to assist me!!!
Big UP!!! StackOverflow!!!
probably error in INCLUDE login.php
My problem was Apache stop working because of ...Skype! Skype actually work on the same 443 and Apache didn't start! I hate this Skype! Bring me nuts for a while.
Installing php5-pgsql worked for me
I am writing a Google Chrome extension. One of my content scripts has a little bug that I can't find and the Google Chrome debugger appears to be useless for this purpose. The code stops on an Uncaught typeError: Cannot set property 'value' of null. I can see this by opening the debugger and viewing the console after the code fails. But my content script does not appear in the list of scripts shown in the debugger at this point. There are a lot of scripts shown there, including a big block of scripts in light blue. But none named "profile.js" which is my content script.
I tried "location.reload(); but it simply returns "undefined." I'd love to step thru this code and find the problem but I can't figure out how to do it. I've set alerts to try to track the problem but once I click on the alert, the script continues with no opportunity to invoke the debugger. Based on the result of the alert experiment, it appears the code is failing at the very end. I presume the code is finished by the time the error is caught and the script is no longer available to the debugger.
I tried adding this line to the script: "debugger;" to try and force the debugger to open but there is no change whatever to the execution of the code. It fails as usual and as usual I can open the debugger, find the console message and the big list of scripts that does not include mine.
How can I pause execution of the code using a line in the code itself? I just want to stop execution of the code at the beginning, invoke the debugger, set up some breakpoints, resume execution and monitor some variables. That seems like a pretty simple and do-able request.
Any ideas?
I get the infamous "Dialogs must be user-initiated" Security Exception when I try to print some stuff in Silverlight. As you can see, the dialog is as user-initiated as can be:
John Papa couldn't help me much out neither, because I don't have any breakpoint set. Mr MSDN thinks it could also be that I'm just taking too long, but this is a demo application just as simple as can be.
Any ideas? I guess it's a Visual Studio quirk, maybe some extensions interfering, as things seems to work when I launch the application outside of it. I first thought maybe the Code Contracts are interfering with their IL weaving, but they are deactivated for this project.
Update: This is just a simple Silverlight application that runs locally from the file system. When I do "Start debugging", Visual Studio creates a hosting HTML file containing the Silverlight app in the Debug resp. Release folder of the project, launches the Internet Explorer with that HTML file and attaches the debugger to it.
Update 2: I also get the same error when I create a web project to host the Silverlight app and create a virtual directory for it on IIS.
I might also want to add that I don't have problems with printing in other Silverlight projects regardless of their hosting scenarios.
Update 3: I downloaded FireFox and it works, I don't get the error when I debug with it. So it seems to have to do with my IE8. I uploaded the solution:
http://dl.dropbox.com/u/10401470/Code/Demos/PrintingDemo.zip
I wonder if anyone can reproduce?
Anyone got an idea to which team I should file a bug report? Silverlight team? IE team? VS Debugger team?
I'm able to reproduce this. You have handled the Click twice, once in XAML another time in code. See your MainPage.xaml
<Button x:Name="PrintButton"
Content="Gotta print 'em!" Margin="8"
Click="PrintButton_Click" />
Don't feel bad about it. I did it last time through a misplaced Print inside a loop.
I've also experienced this strange behaviour. A standard button click event immediately invoking an OpenFileDialog. It would frequently generate the same error when being debugged but would eventually be coaxed in to working when the button is clicked several times.
However when built as a release (or perhaps simply by running the same Xap without a debugger attached to the browser) the problem would go away.
Try to remove
if(SightPaleceListBox.Items.Count > 0)
I had the same problem and found out that the reason was this following line:
cnvsMain.Children.Remove(PrintPagePlaceHolder);
cnvMain is on the page that the user pushed the Print button on (I was trying to remove it from that page in order to add it to the canvas that I was going to print).
My tip: try to comment rows one by one, until you find what row causes the problem. Than try to work around it.
