At first, my permalinks and all worked. My permalinks were in /year/month/post/ format. Today I found out when I try to open an Anspress question, I get a 404. Then I read somewhere I need permalink format of /postname/ to display Anspress questions.

So I changed it to /postname/. Now nothing except index.php?p=xyz is working. All links to pages throw a 404. I tried changing back to /year/month/post/ , but that did not help. Tried going to Permalinks and clicking "Save settings", but that did not help either. Tried a2enmod rewrite (although it has worked before), no help.

I have no idea. It worked 30 minutes ago.
