Wordpress dev to fix some plugins

Hello.

I have a live site which has 3 or 4 plugins which are not working correctly. This seems to have started since the WP v3.5 upgrade but all plugins are up-to-date and verified to be working on v3.5.

I *think* this might be a JavaScript issue. The issues with each plugin is a white "boxes" on a page using the plugin shortcode. eg. a table plugin won't show at all on a page when using the correct shortcode. They all used to work prior to the v3.5 upgrade.

Any questions please ask and please also note, roughly, how many hours you believe this will take.
