I upgraded to the latest version of GD Star Rating just recently, and now one of my URLs (a CPT archive) is producing a 403. The URL ends with 'themes'. Eg: mywebsite.com/themes.
I've gone back through old backups and tested every plugin I can find, and the situation only occurs when I upgrade to the latest version of GD star.
I have deactivated and deleted the plugin but nothing has changed. I've also deleted the tables, to no avail.
Is there another file I should be looking at? My host suggested changing the .htaccess to a fresh upload, but this also did not solve the problem.
