ASP Boilerplate always shows the default error message

I am using ASP Boilerplate (MVC + Jquery) to develop two different online applications. It works very good but there is a problem with ABP exception handler in both of them:
It always shows the default error message (An error has occurred! Error detail not sent by server) also in login validation.
How can I fix this problem?
I tried to debug this error and I realized that the error format that returned from server side is not a valid ABP error format.
please check in your web.config file that shoud be set to On
<customErrors mode="On" />

How do I get ELMAH to log full exception details?

When my server encounters an error ELMAH successfully creates a log of the error including the URL & post data etc but the details of the exception itself are not in the xml log file. How do I change this?
The "detail" attribute of the "error" tag contains the details of the exception.

I would like to use Application_End and Application_Error for logging, but have no global.asax file?

I am trying to write some logging for unexspected session losses, i'm unsure if its a timeout issue or something is cuasing me to loss my sessions.
Following this questions answer ASP.NET SessionState timeout I would like to write my logging in the Application_End and Application_Error sections, but i am unable to find my global.asax file.
The file or Application_End and Application_Error have not show up in my search.
How can i find my global.asax file or Application_End and Application_Error sections, or where else could i log to record the loss of sessions?
Thanks in advance.
Can you check whether you are using the right project template?
Web Application Template or Website Template.
If global.asax file is not there , you can add it manually.

Redirecting errors in codeigniter

I want all codeigniter errors to be redirected to a custom error page. I have redirected 404 errors with $route['404_override'] = 'errorcontroller'; How can I redirect all the other errors such as db and php
You can always use try and catch block and then redirect to your custom error page. But as per your questions, there are some things you should consider.
Redirect will issue a completely new request which is accomplished with the header sent to the browser. For that reason you will not be able to display the error message unless you save that message in session or something.
Some errors results in PHP throwing exceptions while others don't. Some DB interactions error only raises PHP warnings or error. PHP execution may halt but no exception will be thrown. In such case even wrapping the code in try catch will not be any help. However, you can create a custom error handler and inform PHP to use that handler. Then in the custom error handler you are free to throw exceptions or redirect to error page.
you can also use .htaccess to force redirection to the pages you set at specific header codes [404,304,500] etc
Hope this helps!

How to redirect user to a default error page when exception is raised in application_start?

Is there a way to redirect the user to an error page (view) when an exception is raised in application_start method of global.asax? I get a Request object is null message when I try to do a redirect. How would i handle this? I have to raise the exception if certain conditions are not met and I want the user to go to a specific View.
My application is MVC3 based, btw.
Thanks
Application_Start happens before ASP.Net starts processing the request.
You could set a global static flag to indicate the error condition, then handle BeginRequest and check the flag and redirect.
You can refer this page.
The thing you are trying to do is possible via Web.config Just show what page to load when http error 500 occurs.
Edit
Sorry gave wrong url
