Getting a message when crawling

[fonesunlock]

I get the following message repeated alot of times while it's crawling:

Deprecated: Function split() is deprecated in /home/gulteke/public_html/generator/pages/class.http.inc.php(2) : eval()'d code on line 127

First time it's happened, was ok before. Is there something wrong?
