How to remove NEW POST buton from forums 111 ,112 , 121 , 122 (red color forums) ?
I put it forums 111 ,112 , 121 , 122 with no post permision but not hide New Post button.

Y am tock abouth this zone :



and , if it is posible this :




Second level ( forum 11 , forum 12 ) ok
Third level have subforum but not  like second level (without New Post button).

Nobody can help me to hide New Post button ?

It's difficult to remove it only from where u want only.

Why don't you use forums  for that and set compression level to max.
Would look like what u've got now

This is the forum:
www.gsmforum.ro/colyfor

I need New Post button just at last level forum
The others forums level , forums with subforum , the same have this button but here have not post permisions.
With maxim compresion not work.
Thanks for replay

Doesnt work because you 've got subforums
If they were forums and you use max compression will work

Can u use subcat? Why not?
