Joomla "Fatal error: Cannot redeclare jblogerror() in on line 0" - joomla

Here is a weird problem i'm facing; after updating Joomla to the latest version, website failed to up load but, as i've made a backup manually from these folders:
administrator
bin
cli
components
includes
layouts
libraries
modules
plugins
yt-assets
and all the root files, after restoring the backup still the website is not loading and just says
"Fatal error: Cannot redeclare jblogerror() in on line 0" !
Any suggestion? Thank you.

Apparently, the version of jBlog you are using is loading its attempting to load its own classes twice.
Let's assume the jBlog developers already fixed it and you carelessly ignored the warning to ensure all your extensions are compatible before updating.
Are you able to access administrator? Simply go there and upgrade jBlog including any modules.
Else, the issue lies within a plugin. In order to access the administrator and perform the update, you will need to manually disable the offending plugin.
A simple way is to rename its folder: start from plugins/system then plugins/content hopefully you'll have spotted it by then. Look into the subfolders of each and spot any that may be relevant to jBlog (or grep through the folder to locate the specific string)
If you have console access, simply run
# grep -rl jblogerror plugins/system
and you should see all the files that include such string, just rename their main plugin folder. But you could also do all this through ftp and guessing.

go-swagger restapi/configure_todo_list.go - api.TodoGetHandler undefined error

I am a newbie in go and go-swagger. I am following steps in Simple Server tutorial in goswagger.io.
I am using Ubuntu 18.04, swagger v0.25.0 and go 1.15.6.
Following the same steps, there are a few differences of the files generated. For instance, goswagger.io's has find_todos_okbody.go and get_okbody.go in models but mine does not. Why is that so?
Link to screenshot of my generated files vs
Link to screenshot of generated files by swagger.io
Starting the server as written in the tutorial go install ./cmd/todo-list-server/ gives me the following error. Can anyone please help with this?
# my_folder/swagger-todo-list/restapi
restapi/configure_todo_list.go:41:8: api.TodosGetHandler undefined (type *operations.TodoListAPI has no field or method TodosGetHandler)
restapi/configure_todo_list.go:42:6: api.TodosGetHandler undefined (type *operations.TodoListAPI has no field or method TodosGetHandler)
The first step in goswagger.io todo-list is swagger init spec .... Which directory should I run this command in? I ran it in a newly created folder in my home directory. However, from the page, it shows the path to be ~/go/src/github.com/go-swagger/go-swagger/examples/tutorials/todo-list. I am not sure whether I should use go get ..., git clone ... or create those folders. Can someone advise me?
Thanks.
This is likely the documentation lagging behind the version of the code that you are running. As long as it compiles, the specific files the tool generates isn't so crucial.
This is a compilation error. When you do go install foo it will try to build the foo package as an executable and then move that to your GOPATH/bin directory. It seems that the generated code in restapi/configure_todo_list.go isn't correct for the operations code generated.
All you need to run this tutorial yourself is an empty directory and the swagger tool (not its source code). You run the commands from the root of this empty project. In order not to run into GOPATH problems I would initialise a module with go mod init todo-list-example before doing anything else.
Note that while the todo-list example code exists inside the go-swagger source, it's there just for documenting example usage and output.
What I would advice for #2 is to make sure you're using a properly released version of go-swagger, rather than installing from the latest commit (which happens when you just do a go get), as I have found that to be occasionally unstable.
Next, re-generate the entire server, but make sure you also regenerate restapi/configure_todo_list.go by passing --regenerate-configureapi to your swagger generate call. This file isn't always refreshed because you're meant to modify it to configure your app, and if you changed versions of the tool it may be different and incompatible.
If after that you still get the compilation error, it may be worth submitting a bug report at https://github.com/go-swagger/go-swagger/issues.
Thanks #EzequielMuns. The errors in #2 went away after I ran go get - u -f ./... as stated in
...
For this generation to compile you need to have some packages in your GOPATH:
* github.com/go-openapi/runtime
* github.com/jessevdk/go-flags
You can get these now with: go get -u -f ./...
I think it's an error of swagger code generation. You can do as folloing to fix this:
delete file configure_todo_list.go;
regenerate code.
# swagger generate server -A todo-list -f ./swagger.yml
Then, you can run command go install ./cmd/todo-list-server/, it will succeed.

scald.rb results in error (could not find or load main class)

I am trying to run the tutorial files from https://github.com/twitter/scalding/tree/develop/tutorial.
I cloned the 0.17.x branch and current develop branch and haven't had much success with either.
I have also already ran "sbt update" and "sbt assembly" to create the fat jar which is used by this scald.rb script.
Upon running the command below from the root scalding directory
scripts/scald.rb --local tutorial/Tutorial0.scala
I receive either of these errors:
Error: Could not find or load main class Files
[SUGGESTION]: Try scald.rb --clean, you may have corrupt jars lying around
or
Error: Could not find or load main class scala.tools.nsc.Main
[SUGGESTION]: Try scald.rb --clean, you may have corrupt jars lying around
Whatever I try to do I cannot get the scald.rb script to work. I have tried the clean option and many other stackoverflow answers such as setting scala_home in my environment variables and path to scala/bin. Many versions of sbt/scala and nothing works.
Current Software:
-Ruby 2.4.2-2-x86
-sbt 0.13.15
-Scala 2.11.8
-scalding 0.17.x branch

"The selected directory is not valid home for Lua SDK"?

I'm new here so I apologize if this question is breaking some rule or something. But this is becoming a problem for me. I downloaded Intellij and downloaded the lua plugin for it. Well, now I'm trying to configure lua sdk but everytime I put in the location for it, it says "The selected directory is not valid home for Lua SDK"
What is the valid home? What am I doing wrong?
The problem might be that your lua.exe file is actually named luaXX.exe where XX is the version.
In my case it was lua53.exe. I renamed just the lua53.exe file to lua.exe; I didn't rename the rest.
So at first I had:
lua53.dll
lua53.exe
luac53.exe
wlua53.exe
After renaming the file I have:
lua53.dll
lua.exe
luac53.exe
wlua53.exe
With this changed, the Intellij plugin detected the folder as a valid home.

Call to undefined function mysql_connect [duplicate]

This question already has answers here:
Fatal error: Call to undefined function mysql_connect() in C:\Apache\htdocs\test.php on line 2
(2 answers)
Closed 3 months ago.
I just installed PHP and Apache on my home PC. When I try to call function mysql_connect I get:
fatal error: call to undefined function mysql_connect.
I have loaded php.ini where I have uncommented lines extension=php_mysql.dll and
extension=php_mysqli.dll and changed extension directory to extension_dir = "C:\php\ext" - which is the directory where files php_mysql.dll and php_mysqli.dll are. How can I fix this problem?
Output of phpinfo():
http://jsfiddle.net/MMTwA/
After looking at your phpinfo() output, it appears the mysql extensions are not being loaded. I suspect you might be editing the wrong php.ini file (there might be multiple copies). Make sure you are editing the php file at C:\php\php.ini (also check to make sure there is no second copy in C:\Windows).
Also, you should check your Apache logs for errors (should be in the \logs\ directory in your Apache install.
If you haven't read the below, I would take a look at the comments section, because it seems like a lot of people experience quirks with setting this up. A few commenters offer solutions they used to get it working.
http://php.net/manual/en/install.windows.extensions.php
Another common solution seems to be to copy libmysql.dll and php_mysql.dll from c:\PHP to C:\Windows\System32.
Background about my (similar) problem:
I was asked to fix a PHP project, which made use of short tags. My WAMP server's PHP.ini had short_open_tag = off.
In order to run the project for the first time, I modified this setting to short_open_tag = off.
PROBLEM Surfaced:
Immediately after this change, all my mysql_connect() calls failed. It threw an error
fatal error: call to undefined function mysql_connect.
Solution:
Simply set short_open_tag = off.
My PC is running Windows 7 (Apache 2.2 & PHP 5.2.17 & MySQL 5.0.51a), the syntax in the file "httpd.conf" (C:\Program Files (x86)\Apache Software Foundation\Apache2.2\conf\httpd.conf) was sensitive to slashes.
You can check if "php.ini" is read from the right directory. Just type in your browser "localhost/index.php". The code of index.php is the following:
<?php
echo phpinfo();
?>
There is the row (not far from the top) called "Loaded Configuration File". So, if there is nothing added, then the problem could be that your "php.ini" is not read, even you uncommented (extension=php_mysql.dll and extension=php_mysqli.dll). So, in order to make it work I did the following step. I needed to change from
PHPIniDir 'c:\PHP\'
to
PHPIniDir 'c:\PHP'
Pay the attention that the last slash disturbed everything!
Now the row "Loaded Configuration File" gets "C:\PHP\php.ini" after refreshing "localhost/index.php" (before I restarted Apache2.2) as well as mysql block is there. MySQL and PHP are working together!
You have probably forgotten to restart apache/wamp/xamp/whatever webserver you use, you need to do that in order to make it work
Check your php.ini, I'm using Apache2.2 + php 5.3. and I had the same problem and after modify the php.ini in order to set the libraries directory of PHP, it worked correctly. The problem is the default extension_dir configuration value.
The default (and WRONG) value for my work enviroment is
; extension_dir="ext"
without any full path and commented with a semicolon.
There are two solution that worked fine for me.
1.- Including this line at php.ini file
extension_dir="X:/[PathToYourPHPDirectory]/ext
Where X: is your drive letter instalation (normally C: or D: )
2.- You can try to simply uncomment, deleting semicolon. Include the next line at php.ini file
extension_dir="ext"
Both ways worked fine for me but choose yours. Don't forget restart Apache before try again.
I hope this help you.
Hi I got this error because I left out the ampersand (&) in
; php.ini
error_reporting = E_ALL & ~E_DEPRECATED
Be sure you edited php.ini in /php folder, I lost all day to detect error and finally I found I edited php.ini in wrong location.
After change our php.ini, make sure to restart Apache web server.
Just for future reference, copying all these extension files to Windows/System or Windows/System32 is unnecessary.
All that is required is a copy of the php.ini file you edit in the PHP dir to copied to the root Windows dir.
phpinfo will clearly explain the below:
Configuration File (php.ini) Path C:\Windows
Logical sense will explain that php wants to load a config located in the Windows dir. :-)
One time I had a problem while using Off instead of off. And also check the pads one more time... The path has to be exact. Also add the following line to your environmental variable.
C:\your-apache-path\bin; C:\your-php-path\bin;C:\your-mysql-path\bin
If you are in Windows, right click My Computer, select properties, and navigate to the Advanced tab... (is Windows 7). Click on Advanced system settings first then select the Advanced tab and then Environmental variables. Select PATH and click on Edit. Make a copy of the string in a .txt file for back up (it might be empty)--- set your environmental variables... Log out and log back in.
Since mysql_connect This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used.
by default xampp does not load it automatically
in your php.ini file you should uncomment
;; extension=php_mysql.dll
to
extension=php_mysql.dll
Then restart your apache you should be fine
This same problem drove me nuts (Windows 10, Apache 2.4, MySql 5.7). For some reason (likely PATH related), the .dlls would not load after uncommenting the correct exension dlls and extension_dir = "ext" in php.ini. After trying numerous things, I simply changed "ext" to use the full directory path. For example. extension_dir = "c:/phpinstall/ext" and it worked.
I think that you should use mysqli_connect instead of mysql_connect

converter-sample.c contains duplicate main

I'm trying to deploy an application on the mac app store.
I'm working through the process of adding the code to validate the recipts
In accordance to the documentation I've compleated the follwing steps
Installed asn1c using sudo port install asn1c
Created a file modlule.asn1 in a directory asn1c_dir from listing 1-1.
cd asn1c_dir
asn1c -fnative-types module.asn1
Then in Xcode "add existing files" and add the asn1c_dir directory
Try building, but I get ~900 errors
In the target build settings, I check the box next to "Always Search User Paths"
I now get a single error saying "Duplicate symbol _main in /foo/bar/ppc/converter-sample.o and /foo/bar/ppc/main.o
I've tracked this to the fact that it looks like the file converter-sample.c declares it's own int main() function which is bad right?
any help would be appreciated.
So for metric reasons, I'll answer this question.
converter-sample.c is an unnecessary file. Delete it. Go about your life a happy person.
