Hello,

A white page or a page with a 500 Internal Server Error is, in fact, either a .htaccess issue to a PHP fatal error in disguise.

First, let's see if it is a .htaccess issue. Try renaming the .htaccess file in your site's root to htaccess.bak If there is a .htaccess file in the site's administrator directory, try renaming it as well. If that solves the problem, the issue was with a directive in your .htaccess file. We'd like to recommend you to try removing directives from your .htaccess until you find the one which causes the problem.

If that doesn't help, the error you are receiving is in fact a PHP error in disguise. First, check your server's error logs (not the access logs) immediately after visiting the page which throws the error. There should be an exact description of the PHP fatal error which occurred. Sometimes you can find the error messages in files called error_log or error.log inside the site's root and/or administrator directories. If unsure about the error log location, please consult your host. Most likely the error logs are available in your site's hosting control panel.

If your host does not give you access to the error logs and you have access to the Joomla! administrator area, please log in to your site's back-end, go to Global Configuration, click on the Server tab and set the Error Reporting to Development. Try visiting the problem page again.

If you still get a blank page, edit your configuration.php file and put the following code right after the final closing curly brace ( this is what a curly brace looks like --> } ) but before the closing PHP tag (it looks like ?> that is a question mark and a greater-than sign):

ini_set( 'display_errors', true );
error_reporting( E_ALL ); 

Try visiting the problem page again.

If you still get a white page, please remove the two lines from your configuration.php file. Edit the .htaccess file in your site's root. If you don't have a file named .htaccess create a new one. Beware that htaccess.txt is a DIFFERENT FILE and will NOT work! Add the following to the end of the file:

php_flag display_errors On
php_value error_reporting 32767

and retry loading the problem page.

If you still get a white page, remove the two lines from your .htaccess file. Now, create a file called php.ini with the following content:

display_errors=on
error_reporting=E_ALL

and upload it into your site's root and your site's administrator directory. Retry loading the problem page.

If that fails again, remove the php.ini file and create a file named .user.ini (note that it's dot user dot ini, the leading dot is important) with the contents:

display_errors=on
error_reporting=E_ALL

and upload it into your site's root and your site's administrator directory. Wait for 10 minutes. Waiting is important, .user.ini files do not apply immediately. Retry loading the problem page.

IMPORTANT: Sometimes the error won't show. Edit your configuration.php and find the line starting with public $error_reporting and set it to:

public $error_reporting = 'development';

This instructs Joomla! to enable maximum error, warnings and notices verbosity. In 99.9% of cases it will result in the error messages being shown on the browser.

If you still get a white page, delete the php.ini or .user.ini file your created and consult your host. They have to provide you the PHP error message, file and line it occurs (along with the error's backtrace) themselves.

Please note that if you can not understand what the PHP error message means, just copy and paste it here verbatim so that we can take a look and point you to the right direction.

By enabling the error reporting mode, as previously suggested, it seems that the problem is caused by the system plugin nrframework. By renaming it (so it's disabled) you can get access to the backend. The frontend still gives you a 500 error, but at least you can get to your backend.

That plugin seems to be a framework for another extension developed by www.tassos.gr , you should review your installed extensions and try to install again the extension from that developer.

Regarding the frontend, try replacing current .htaccess with Joomla default one (remember to use your browser in incognito mode to avoid caching issues).

Can you please double check your configuration.php if the variable $live_site is empty or has a value in it?

The $live_site variable should be empty. Please remove any contents and try again. That's the source of your error.

For the records, in 99.9% of the cases that variable should be empty, in almost 15 years of working with Joomla and doing tech support I never had the need to fill it.
