suddendly the stars are not shown anymore: users cannot vote, and they see only "Rating: 10.0/10 (2 votes cast)". No stars.
I tried to upload fresh version, no changes.
I tried to disable plugins, no succesful.
I tried to switch template, same problem.
I update from 3.5.x to 3.6, nothing changed.
In 404 errors I see the page
./wp-content/plugins/gd-star-rating/css/gdsr.css.php (it shows me 404 error) but checking in the server the page is available. Should be this the problem? How to fix?
