Hey again,
From looking into the problem it’s not actually related to just one theme. Basically any theme which loads a jQuery of 1.9 or above breaks the AJAX loading. This seems to be due to the depreciation of live which is now replaced with on (more info here: http://api.jquery.com/live/ )
Would it be possible for the plugin js in voter.js to be written to utilise the new event handler in jQuery 1.9? It would seem to make sense as even by default WordPress now includes jQuery 1.11.3.
To help anyone who may need this:
The plugin is indeed written for jQuery < 1.9 as it uses some functions removed since 1.9 however the problem I’ve had was caused by my theme loading jQuery > 1.9 after the plugin. WordPress itself loads > 1.9 BUT also includes jquery-migrate.
Basically as long as you stick to the core WP loading of jQuery you’re fine. Not technically an issue with the plugin but updating the js to use the newer functions in jQuery > 1.9 might be worthwhile.
