Getting PHP Errors after uninstalling a hook?

[Hannibal Lecter]

I tried a hook called 'Global Forum Message' and after installation it worked, but in all my sub-forums I received a large amount of PHP Errors. 

my site is: http://rs-ct.net/ check any of the subforums.

 

I uninstalled and disabled the hook but now the PHP Errors are still coming up. The only thing I've changed is I was getting errors while trying to utilize (SOS34) Group Color on User Link

I changed the following:

the sos33_gchovercard_forumIndexTopics.php file in the hook folder of your forum root.

Replace :
 

$data['last_poster'] = IPSMember::makeProfileLink($lastposter, $data['last_poster_id'], $lastposter['members_seo_name']);

with :
 

$data['last_poster'] = IPSMember::makeProfileLink($lastposter, $data['last_poster_id'], $lastp['members_seo_name']);

 

 

But it worked normally after that until now. Some of the PHP Errors I'm getting are as follow:
