No, it just kept saying “invalid file name”–but I just tried removing the period instead, and it let me rename it to “htaccess” …but still no luck. Now the website displays a 500 server error instead of the WordPress install page.
You probably have too many redirects (e.g. a domain that redirects to a page that redirects again.) Try using your file manager to get rid of as many redirects as you can, then figure out which ones are necessary before you put them back in.
I have tried renaming my table prefix, renaming all databases, and done a MySQL repair of the database.
My web host won’t allow me to rename the .htaccess file. Any tips?
