 * I installed this plugin yesterday when I had 3 posts online, but today I uploaded
   a few more test posts on my website and suddenly I got this error:
 * Fatal error: Unknown: Cannot use output buffering in output buffering display
   handlers in Unknown on line 0
 * My sidebar doesn’t want to show up anymore. I chose to show 3 thumbnails/popular
   posts in sidebar.
 * Could anyone help me – how can I solve this issue?
