Attempting to edit any of the fields of the profile in the User Control Panel produces an HTTP 500 error. Editing avatar or signature on their respective pages works fine, but everything on the "Edit profile" page produces this error.

We know what the problem for this is, unfortunately it's a fix that will take a decent while to get sorted (and isn't something I am capable of doing myself, so can't make any sort of promises as to the timeframe.)
