So my provider recently upgraded from php 4 to php 5. Initially we got the "Fatal error: Call to a member function Execute() on a non-object"-error, but we managed to bypass that with some changes in the sessions.php-file. Shortly after we began to notice that some orders didn't go through. You were able to create an account, go through the checkout process etc, but the order didn't show up in the admin. I know this sounds very vague, but have anyone had a similar problem?
