whenever i click edit post this comes up Fatal error: Call to undefined function fetch_htmlchecked() in /home/wrestlin/public_html/editpost.php on line 817
this has started happening since i installed a HIDE PLUGIN earlier on today if anyone knows how i can fix this please let me know below :S

Re-trace the steps that you used while installing that plugin. Maybe you missed adding some codes or you've added the codes at the wrong place

+ mention which forum software this issue is related to :S

Your file maybe messed up..

just uninstall that product and remove all files you uploaded via ftp
