I've purchased 10 domain licence but when I go to upload a template, I get the following error message:

Deprecated: Function split() is deprecated in C:\wamp\www\domain\cuteeditor_files\Dialogs\upload_handler.php on line 77

The template is uploaded OK and available but I cannot put this error message up on to my live website.

Also, how do I find out what version I have and how do I install updates, please?
