Hi,
Kindly check whether you have the seller user group in your joomla administrator. If seller user group is not listed then you need to create it by Go to the joomla adminstrator -> Users -> Group -> For creating the new group click on the new button and select registered as its parent.
You can create the sellers by two ways:
First, Seller can register from the frontend. Second, You can create the seller by the joomla admin group.
Thankyou
