Rate module: rate icon disappears and no vote is recorded I am having a problem with the rate module. I have implemented it on node 'project' and it appears. When I click on 'thumbs up', the icon disappears. It looks like the AJAX is not working.
I was finally able to resolve this issue by enabling Clean URLs (configuration -> clean URLs).  Note, if you are prompted with a Clean URLs test that inevitably fails, you will likely need to uncomment the "RewriteBase" line in your .htaccess file.
