Can I upgrade ThumbsUp v1 to v2?
No. Well, you can, but you have to uninstall v1 completely and then install v2. ThumbsUp 2.x is not backwards-compatible with version 1.x.
Does ThumbsUp work on PHP 4 ?
No. PHP 5 is required, with the PDO extension enabled. ThumbsUp will not work on PHP 4 .
How can I log in to the admin area?
You need to configure a username and password in thumbsup/config.php.
It keeps on spinning when I vote. Or why is the ajax request not working?
Make sure your “url” setting in thumbsup/config.php ends with a forward slash.
Also, only use a single domain, either with “www” or without.
