I had a look at a couple of articles online like

https://www.akeebabackup.com/support/admin-tools/14196-opencart-and-akeeba-admin-tools.html
I was told by the mijoshop developers.
Also you must prevent paypal links in your firewall settings
Otherwise system CANT get the paid or completed status updates from the PAYPAL.
Do I even need to do this?
Thank you.
