Thanks Topanga but I must ask you to excuse my ignorance and tell me where should I put that code into.

Best Regards

in _main.php

Look for the first line, and just add the second line

That looks incredibly awkward to me. Could you please explain what all those numbers mean?

Thanx in advance,
Sebastián

They are just category numbers

Sorry for bothering again, but --does this mean that you must alter that code every time you add or delete a category?

And how many times do you add a category in your linkblog ?
To me that amount seems very limited

You're right, of course. But now --how do I know which are the numbers for each category? The interface doesn't show them.

Go to your Categories tab, select your linkblog, and run your mouse over each category name. The cat_ID will show up at the bottom of your browser window because it's part of the link.

General question on this issue: Why do you hide blogs by category? (cf. http://forums.b2evolution.net/viewtopic.php?t=3591 also)

If someone creates a new cat on the hidden blog, you have to update your array of hidden cats.

So why not looking up the ID of the blog the current item belongs to and exclude by blog ID like this:

$excluded_blog_ID = array(2,11,42); // can be put in a config file?
    // Define List of blogs to be excluded from blog all
    if ($blog == 1 && in_array($Item->blog_ID,$excluded_blog_ID ) == true){  
    // if we are on blog all and the blog ID of the current
    // item is on the exclusion list do nothing 
    }
else { //otherwise show item
         // put the normal stuff here
       }// close bracket before END OF POSTS bracket

(note: I'm not a programmer, please don't blame me for weird code ;) )

Because posts aren't in blogs - they're in cats and cats are in blogs. If you think about it a bit it'll make sense. Else how could you post something in multiple blogs?
