[<MG>CP]

Quick note that it worked for me for anyone else looking to solve this problem, it beats installing, uninstalling, disabling, etc. Thanks for that!

Go to Plugin Manager, find Hook Location : postdata_presave

Then click SpamBuster: Normal posts check

Change

PHP Code:

$GLOBALS['sbhits'] = sb_test($this); 


PHP Code:

if ((strstr($_SERVER['REQUEST_URI'],'admincp') !== FALSE) && (strstr($_SERVER['REQUEST_URI'],'modcp') !== FALSE)) 
{
$GLOBALS['sbhits'] = sb_test($this);
} 


Worked for me, should work for you.
