I've been using your plugin for a few months, and I love it. However, something went wrong today and the related thumbnails started displaying strangely after updating a few plugins. I deactivated the related thumbnails plugin, but the related thumbnails did not disappear... and I see the following error message when I got to the settings page, and on the website.
Warning: in_array() [function.in-array]: Wrong datatype for second argument in .../public_html/wp-content/plugins/related-posts-thumbnails/related-posts-thumbnails.php on line 379
So I went the next step and deleted related thumbnails plugin, however, the thumbnails remain - and they appear on every page and post (even though I have only ever set the thumbnails to display on posts), and what's worse, display on the website front page.
Please help me! How do I completely remove related plugins from our site.
