I am running roundcube V1.3.5 on a MediaTemple Gridserver instance. It seems to have gone haywire - I can't see half of my folders, some are greyed out. It probably makes sense to upgrade to a latest version, but the instructions for doing so, talk about backing up my webmail database. (MySQL) I suspect that the database backuped or otherwise is corrupted. I can go to the same mail account directly from the IOS mail app on my iphone or ipad, and it works fine.
I am assuming that if I use the current or even the backedup database, I will inherit it's corruption. Is there a way of "decorrupting" the database, or if I do a fresh install, will it pick up all of the structure from the imap Deamon?
