I'll go directly to my problem

I'm using jqgrid php module. Im my local server (wamp) it works like a charm but when i upload it to my hosting (a2hosting) and there i'm getting this error when trying to load the grid

Warning: Please contact support about failure in/home/pablinic/public_html/dev/ruleta/admin/php/jqUtils.php on line 1

Fatal error: Class 'jqGridUtils' not found in/home/pablinic/public_html/dev/ruleta/admin/php/jqGrid.php(1) : eval()'d code on line 1

i don't even know what kind of source i should post so anyone can come up with a solution but this is freaking me out.

i hope somebody knows the solution to this problem

thanks!
