HTTP ERROR 500 on Dashboard

HTTP ERROR 500 on Dashboard

Hi,

I am using Moodle 4.4.3+

Recently after upgrading my moodle instance I am facing this error on Dashboard:

HTTP ERROR 500

All other pages are working fine.

If I disable "Calendar" block, Dashboard starts responding.

I enable debug and it gives me this:

Please help...

Hi Aditya

We had a 500 error on some users dashboard a few months ago (at that time, we were still on Moodle 4.1). Removing/disabling calendar block made the dashboard working again (as in your situation). After some digging around, I found out that the error was caused by a file added to a calendar entry in the description field in one of the courses the affected users were enrolled (it was actually a deadline for an assignment) - this file was base64 encoded. After removing this base64 encoded file in the text area of the calendar entry description, the dashboards of the affected users worked again.

I'm not sure whether this is helpful in your situation, as 500 is a generic error...

Best,

Samuel

In addition to what has already been suggested, I see "/theme/academi" in the debug output.

Theme related?

On a temp basis, add a line to config.php to force the site theme to 'boost' as that is a theme that comes with core moodle.

$CFG->theme='boost';

See if the issue goes away - and you can regain access to the site.

Thanks Ken smile
I will check that base64 encoded, I have lots of courses smile
There is no $CFG->theme='boost'; entry in config file.
