[Plugin: Artiss Content Reveal] Inserting code drops sidebar

When I insert the code into a post, the function works perfectly. But my sidebar is bumped to the bottom of the page. If I remove the code, or put the post back to a draft, the sidebar reverts back to normal.

I took the plugin code out for now, but I can put it back and post a link if that helps.
