I tried some changes in the blog settings today. Some have worked but one totally screwed up the blog. For a few hours the front page of the blog was accessible, but links to old posts and the RSS feed did not work.
If you have a WordPress blog, stay away from the Hotlink Protection feature in cPanel X. I’ve found that many others have had similar problems. If you wound up here because of running into this problem, I found out that this command changes the .htaccess files, and that turning it off does not correct the changes causing404 errors. It took a while but I found a real easy fix. Go to the Dashboard and choose Permalinks in the Settings section. You don’t have to make any actual changes but click “Save Changes.” This should force WordPress to regenerate corrected .htaccess files.
I believe everything is working now but I have stuck with some other changes, so let me know if anything doesn’t seem to work right. If you report a problem, let me know whether you were signed in to the blog, as the cache settings work very differently depending upon whether you are signed in.
