Forums / Cotonti / Extensions / Support / Page siblings errors

So I decided to try the page siblings plugin on my site.
 

Because the output was to long I deinstalled and removed the plugin. Guess what haooens next..?

Although the plug-in isn't even availible anymore, I still get these errors on top of every page:
