I missed to specify I was talking about Sharepoint 2013 online.

Is your advice still valid?

Thanks again 

You can turn on your PHP errors with error_reporting:

 

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

 

Edit: It's possible that even after putting this, errors still don't show up. This can be caused if there is a fatal error in the script. From PHP Runtime Configuration:

 

Although display_errors may be set at runtime (with ini_set()), it won't have any affect if the script has fatal errors. This is because the desired runtime action does not get executed.

 

You should set display_errors = 1 in your php.ini file and restart the server.
