MyBB Community Forums

I have upgraded from 1.1.7 to 1.2 - no problems during the upgrade process, however when browsing the forums, I cannot view any threads. It says, "Invalid forum". I can though view the forums.

I have checked the id relation in the database, and they're correct. Forum permissions are so. What do I do?

I have solved the issue.

In the inc/config.php file it states you can store cache to files by changing the value for $config['cache_store']. However that results in the above issue with "Invalid forum". I tried rebuilding the cache, which had no effect, so rolled back the value to "db", and problem solved.

Have you set the CHMOD of inc/cache folder to 777 when changing that config?

Yes, and cache files were generated. I didn't run through all the settings in the inc/cache/forums.php file, but it looked right, pointing to the correct forums id.
