I noticed that if I exclude one(or more) category from the main loop in Index.php file then posts for excluded category(ies) not appearing on main page (as expected) ,but still considered by loop when creating links to NEXT and PREVIOUS pages. For example i have 10 posts and number of posts to show is set in admin as 5. Also , my 2 recent articles are in excluded (from the loop in INDEX.PHP) category. Then when on home page i have only 3 posts and link to NEXT page - having 5 posts. My question is : is it a bug? or i miss something? or this is normal.. I do not use any other loops in INDEX.php file.
