Hi Rafael,

First off, let me say what a great product! Nice and tight (not a lot of overly-impregnated options to get hung up on for the users, etc.) and very good usability.

Ok, that said, we've encountered our first problem with a new install of v2.1.4 (using the "Automatic" method/default file base). It seems that somewhere during the use phase of the application, the native data became corrupted, and upon restarting it in Tomcat, we now get the following 500 error:

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

Apache Tomcat/5.0.28


One idea that our Open Source Guru had was to reinstall JForum using MySql as the database - do you think this is a valid approach, or have you seen a similar situation that could help us debug this?

Best Regards,

Yep, MySQL is a better shot. HSQLDB will be OK for hotsites, that just run for a few days and don't have tons of messages.

Anyway, this lock problem you can solve by deleting the lock file from WEB-INF/config/database/hsqldb.

And, btw, thanks a lot for the good feedback. Let me you any suggestions you may have.

Rafael
