HELP! Sidebar widgets moved to bottom of all pages and posts

I noticed hours ago that my sidebar widgets have mysteriously moved to the bottom of the page on all pages and posts of my site https://www.coziggy.com. The only things I’ve done since I noticed this are installed then uninstalled the GD Star Rating plugin (in fear that this caused the problem) and added a few lines of text to this post.

I tried deleting all content on the sidebar.php and widgets.php pages and pasting in the original code from the theme file I received when I first purchased it, but that didn’t work. Unfortunately I’m not an expert with php or any coding language for that matter, so I couldn’t uncover the problem there.

Any help with this would be much appreciated, as it’s driving me crazy. I found a few other support posts relating to the problem of widgets moving to the bottom of pages but none seem to apply to what I’m running into.
