Can't save products on front end

Hi

I can't save products on front end as a vendor. I created a group called vendors with the same access rights as registered. When I log in, and go to front end Vendor Dashboard. It will not save products for me. I get the following error at the top of the page, when I click on Apply or Save:
Error
The access to this page is forbidden

Above that though, it says:
Message
Successfully Saved

But no product has been saved.

I can however save products as a superuser on the front end.

Hi,

You may have some ACL or a configuration issue ; the message is not provided by HikaMarket but by Joomla.
Would it be possible to have details about your website, like the HikaShop & HikaMarket version number you're using, the Joomla version, etc.

Regards,

I think I may have found the issue. I am using 'MightySites' on my site to allow the one joomla installation for subdomains. The issue I am having is in my subdomain. When creating a vendor in the backend, of the subdomain, its not showing the ACL.
