I accidentally deleted a user so all their posts went to the trash. After republishing them I noticed some posts have the "Exec-PHP WYSIWYG Conversion Warning" message and the posts don't get published at all, they get redirected to a 404 Page not found page.
I've recently upgraded to WordPress 3.5 and nothing changed.
I've also gone into the user profile to disable WYSIWYG Conversion Warning and turned off the WYSIWYG editor (separately first and then at the same time) and again the post is not viewable from the edit post page (clicking "View post") or by typing in the direct URL.
Any suggestions or ideas are most welcomed! I'm fairly new to WordPress but I'm learning on the fly!
