"unsupported format character 'q' " when registering or reseting password

Hi,

Checked the known issues, but it doesn’t seem to be the same as the ID field issue (tried the fix mentionned). I also don’t think it’s the same as the log-in issue I just bumped. Sorry if I’m wrong, though.

When trying to register a user or when trying to reset a password, I have a 500 error right after submiting the email address. I have this in the OSP log (same message in both cases, except for the /register being /reset accordingly of course).

The database was originally created in 0.7.something, I could’ve missed an upgrade detail. :slight_smile:
