Yes, almost all hostings do. To make sure all tech requirements are met please upload m1info.php to your Shopping cart root directory. Then open it in a browser. You will see a table with all requirements, checked for your store. If you see any description in red - please check it. Most likely this requirement is missing.

You can find m1info.php here http://support.magneticone.com/files/m1info.zip

and in your installation package as well.
