The AddThis plugin (and even the copy-paste code from addthis.com) doesn’t seem to be working with the Backstreet theme we're using with WP 3.4.
When the AddThis plugin is used, the AddThis widget doesn't display at all, and many functions of the theme fail, including hover effects, slider, news scroller, twitter widget, carrousel layout, etc. Disabling the plugin causes all to return to normal.
Adding the copy-paste code from addthis.com results in the same "broken theme" behavior, although the AddThis widget appears but is not aligned correctly.
We've removed the plugin for now, but here's a test page of the site with the copy-paste code remaining. Perhaps someone could take a look and lead me in the right direction to resolve the apparent conflict?
Doesn’t look like a conflict between AddThis and any other plugin, as the problem with AddThis exists even with all other plugins disabled. Seems like a JS conflict with the theme, but I’m not skilled enough to troubleshoot that without a little guidance.
