Opencart is a third party script, it is offered through softaculous for easy install, but we do not support the scripts available through softaculous, or any other third party software. For support with those third party scripts you would need to contact their respective support channels.
We can not test all third party and our staff does not know how all of them work, some of our staff may have personal experience of a few scripts though and be able to offer minor help or advice about them.
