I'm sure this has come up before, but I've not been able to find the relevant page.
Basically I'm getting a 500 Internal Error. Delete the htaccess file and the site is back up. Go to the permalink options and get rid of the permalink structure and I'm pack in business.
The SECOND I decide to have anything apart from the default and an htaccess file is present in the root directory I get those 500 Internal Errors again.
I haven't really done anything to instigate this so I'm not sure what's triggered this off. All my pages don't work now either.
Anyone got any posts where something similar has happened?
