in your config.php file, and also try creating a new style with no parent, and see if you still have the problem.
Disabling the Hooks didnt work.
About the styles, no matter which Style I use, these Forums are never visible "inside the first level Sub Forum". Not even in the default Style that comes with vb!!
Any caching being used on the server? Did you select to use that caching in the config.php file also? Can you see the sub-forums in the database? Are they shown in the Forum Manager and not set to Display "0"?
hmmmmm, no caching AFAIK. I checked the config.php and it seems there is also no caching activatzed.
I can see the Sub Forums in the Database, Forum Manager AND when im on Forumhome (domain.com/forum) .... but not when im clicking the level 1 Sub Forum :/
Please dont forget, this test area is a 1:1 DB + Files copy of my live site, where everything works
