A Blank White Page Is Still An Error Page

Sometimes, due to a PHP error, a Joomla Extension can stop working and, without displaying an error, lead you to a blank page.

In that case, to find out why, do following:

1. Check server error logs (not access logs) if you have access to them. (cPanel or other control panels often allow this)
2. Go to Joomla Administration -> Global configuration and enable Error Reporting to Maximum, you can also turn on debugging. – try the action again – if you still get a blank page then goto 3
3. put the following code at the END of the configuration.php file BEFORE the closing ?>

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

4. Check the source of the white page – there might be still some HTML/Errors in the Page Source (Look in your web browser for the “View Source” option)

One of these should give you a nice detailed error message – which you can either email me directly or Google to find a  solution

Remember this: A White Page is just an Error Page where the error message has been supressed by your configuration.
