MyBB Community Forums

Export the tables in the ACP. You can't just export the posts and uses tables though. You need the threads table otherwise the posts have nowhere to go. You also need the forums as the threads need somewhere to go. Then you'll need the forum permission tables. You'd be far better off just fixing whatever you've setup wrong, if you can explain what's actually happened we might be able to help.

The themes are all messed up, I reinstalled the theme but there is no deafult theme. So there are no stylesheets

See my other thread:
http://community.mybboard.net/thread-66506.html

I'll merge these threads then.

That's not worth installing again over. Install a test forum and copy across the mybb_templategroups, mybb_templates, mybb_templatesets, mybb_themes and mybb_themestylesheets from the test forum to your live forum, so all these tables are as they were to begin with, and then it should be fine.

...why didnt i thinkof that lol XD
Thanks matt
