Just posted on wordpress support forums.
When I create a htaccess file using options/permalinks, a message says the htaccess file is not writable, so I have to cut and paste the code, save it as a file and upload. I do that by saving it as a.htaccess as a text file, upload, rename to .htaccess, then chmod to 666. It then worked ok.
I used it for a couple of days no problem. Then a few hours ago I was clicking around the options area (looking for the spam options actually). I clicked on the Permalink page, DID NOT DO ANYTHING, tried to go out of it then it returned a “INTERNAL SERVER ERROR 500”, etc.
