After upgrade to 2.1, can't login

After upgrade to 2.1, can't login

I just upgraded a copy of our live site from 1.9.10+ to 2.1+, and although it initially left me logged in, once I reopened the browser, it wouldn't allow me (or anyone) to login again. I followed all the defaults for settings on upgrade, and deleted all mods/blocks that were incompatible with 2.1 prior to completing the upgrade.

Here is the error: Error writing to database

Stack trace:

Did you upgrade to 2.0 first (like the release notes suggest) and, if you did, did that work ok?

Is this manual auth or some external method? The only way you get to where the error occurred is if the user does not exist in Moodle but is authenticated by an enabled auth plugin. It then tried to create the new profile which is where it is failing.

Regardless, find the installation faq in the docs and work through the "I can't login" points - if nothing else to eliminate them.

Let us know how you get on!!

Tried going right from 1.9+ to 2.1+, so I'll try again with 1.9 to 2.0 first and see what happens.

I'll also re-enable the manual admin user before upgrading so I can verify that the LDAP didn't get borked.

Thanks for the ideas.

As a general point - your primary admin should *always* be a manual user. Otherwise, this sort of thing happens one day wink
