Hiding a category from index : success but posts unreachables
 

Hello again.

In my blog : http://www.lebardessciences.com I have a glossary category (Lexique, id=30). I do not want it to appear on the index page.
By searching here I found that adding

in ATO (the LOOP section) worked like a charm : all the posts from cat30 were removed from my index. Fine.

Now the problem is : when I clic on this specific category, I can see the list of the posts titles but when I clic on one of them, the post content is missing ! I can only see the comment box.
If you want to check : http://www.lebardessciences.com/category/lexique/

I think this is because of that line I modified in the loop, because if I change
in
(any number) the problem is solved.

I think I should add something which tells the browser not to display the posts from cat 30 EXCEPTED when I clic on this cat 30. I looked something with is-category('30') but nothing worked so far.

If anyone knows...let me know in turn ;)

OK I searched a little more and I found a post from Juggledad saying that should be added. So i put this line instead of the first one but nothing worked, and my homepage was full of error messages. Keep searching.

looks like you fixed this. are you set??

Hi,
I just tried the "mcatFilter" wordpress plugin. It worked fine.
However i'm still interested in an easy solution, to improve my knowledge and to get rid of a plugin if I do not really need it. So any advice is welcome ;)
