Hey guys...I have over 20 blogs and I am very familiar with Wordpress, but this is baffling me. I have setup www.illstyling.com and after I reset the permalinks to a new structure all my links to the individual posts stop working, after working for a while. Not too sure what's going on.
It's a .htaccess issue. CHMOD the .htaccess file for that certain blog to 777 and modify the permalinks again. If my guess is correct, it should work without any more issues. Hope this helps,
