This isn't a question, but anyway: my site stopped working today on Hostgator. Any link I clicked resulted in a 404 error, though the home page worked.
Even though my .htaccess file had worked before, it suddenly stopped working. Now I had to add
RewriteBase /qa
to get it to work correctly.
Strange. Not sure how it's possible that it worked before. The install of QA didn't change, nor did the location of the directory, etc.
