Thank you! This resolved my same issue I had too. I deleted (actually, renamed to htaccess.txt.bu) my .htaccess file in the root of WP install. I was also using WP as a subdomain.
BTW, I also previously tried commenting (adding # before each line) the 2 lines of the .htaccess file out, but that didn’t resolve it. I had to remove the file.
Thanks!
