Moodle Fatal Error

[Wildebeaste]

Hello folks,

I'm having problems with an installation of Moodle (created from a backup of the database and moodledata).

When any user logs on, they are met with a blank page. Nothing at all - page source is also empty. If they then use the browser 'back' button and click on the 'Portal' crumb on the top-left they are in and Moodle works fine.

I've turned the debugging on, and there are several errors, with this bringing up the rear:

Fatal error: Cannot access empty property in .../moodle/enrol/database/enrol.php on line 42

Can anyone suggest a solution? There are several pages on the Interweb referring to this but no solution that I can find.

Thanks.

Anyone got any idea?

Having checked the enrol.php file it might have something to do with roles. Do you still have the old moodle running. If so copy the enrol.php. Otherwise did you have another type of enrolment turned on.

Only other thing I can think of it that there was another type of role created on the old version i.e. student2 and that it is trying to apply the settings to the user but can't find it.

Hope this helps

Did you by any chance switch on "external database" in site admin>courses>enrolments? This can bring up this error if it's enabled but not configured.

It would be worth checking the file permissions. Is your moodle hosted on Linux?

Cheers for the replies guys I'll take a look at those when I get a chance

Your a star that did the trick unticked the external database(which wasn't configured) all OK now
