Guys, I don’t want to be in the middle of it, everybody seems to be getting pretty defensive on the issue, while in the end the only thing I need is to have the issue resolved. I don’t want to rewrite your answers and I copy them the way they are to hosting support.
Here is their reply.
This is a PHP and not a server function. You can refer the developers to the PHP manual for more information on how to use the function:
http://php.net/manual/en/function.session-save-path.php
If they are unable to resolve the issue, we would recommend you to consult with a professional developer who can modify the syntax of the test php script session_test.php so that it can work properly with the desired sessions folder.
If there is anything else we can help you with, please contact us again by posting a new ticket.
