I've been using codoforum v3.4 for my gaming comunity website. I had about 100 users, but only 30 topics, with about 15 categories. Today 90% of the entire database is gone and lots of the pages that can be navigated to throw PHP errors. I have no idea how this happened, and was wondering if anyone else has experienced this before?

Maybe your hosting company has changed your PHP version or something else?

No, that's not it because it's hosted on my CentOS VPS and I have not changed anything.

@koenrad you think you got hacked if you didn't change anything?

Can you check what exactly is gone ?

The 3 tables that contain the forum data is
codo_categories
codo_topics
codo_posts

Can you check what data is present in these tables ?
