APTHost changed their php to phpsuexec and you 'll need to make major changes to your and php.ini to get vShare to work.

Here is the sample php.ini they sent me. Notice the ZEND stuff at the bottom and if you had your max_upload set to something different, you'll need to change that too. I don't know WHAT in this php.ini is different than what I was previously using, but this one works.
