[Plugin: WordPress Related Posts] no thumbnails

The plugin is looking for thumbnails attached to the posts using custom fields instead of the newer post thumbnails plugin which has been around since 2.9. You can modify the plugin yourself using the instructions on this thread.

Or else you can try out a different plugin. As long as you’re not using Disqus and SEO pager, I highly recommend YARPP.

Also, I notice that on the back end, all my tags on my posts disappeared when I activated this plug-in. Does that mean they’re no longer tagged? Should I be worried? I’m using wordpress 3.0.1. Some help would be great. thanks so much.
