error deleting category

[ashna]

Hi,

 

I am getting this error in admin while doing quite a few things.

This one came while deleting a category. Although its a warning any ideas whats causing this.

 

 

Warning: set_time_limit(): Cannot set time limit in safe mode in /home2/ashnacre/public_html/quickpos/catalog/admin/includes/functions/general.php on line 733
