Moodle Question:

There are a few ways you can enable or disable debugging on your site. If you are able to login as an administrator and access the Site Administration block, then the easiest way is to go to Admin->Server->Debugging and set it there. There are several options - the most often recommended setting for debugging is 'ALL: Show all reasonable PHP debugging messages'. To disable debugging, simply set this to 'NONE: Do not show any errors or warnings.'.
