TCExam should automatically resync the password. Are you using the latest TCExam version?

An easier option is to backup the DB separately and copy the entire TCExam folder over.

I may include an option to backup all the files too but this may require manual restore anyway.

Thanks for the suggestion.

This will require a change in the DB as the current table field is designed as boolean. This feature must work with all supported DBs.

Would you please elaborate on that?

Are you asking for the students to be able to write math formulas on their answers?

It looks like those cases are not properly handled when using Postgres. I will need to investigate how to make those queries working with all supported DBs, as your suggested...

tcpdf was changes while ago. Is this still a problem with the latest version?

I believe this has been fixed. Closing.
