[Schneeflocke]

Okay, thanks for your help.

But, nothing works.

I have CategorieIDs -100, 122, 126
and
ChannelIDs - 136, 186, 119, etc.

I tried the code:

#forum136 .posts-count,
#forum186 .posts-count,
#forum119 .posts-count,
#forum120 .posts-count,
#forum121 .posts-count,
#forum124 .posts-count,
#forum125 .posts-count,
#forum138 .posts-count,
#forum187 .posts-count,{
     visibility: hidden;
}

and:

#forum100 .posts-count,
#forum122 .posts-count,
#forum126 .posts-count,{
     visibility: hidden;
}

I insert it in the CSS-Editor (css_additional template).
But the post continued to be counted.

It is very important to hide the count. So, maybe I need a manual for ... idiots
