Thank you so much for your thorough reply!
I am actually still struggling with these issues and I am starting to think that maybe my MultiVendorX plugin is not activated?
1) When I registered as a Vendor, then my admin account didn’t receive any notification and I didn’t receive any welcome or login information emails on my vendor email. I checked my admin email settings too.
2) The “submit product” is activated for the vendor, but it still doesn’t show the option on the vendor’s account.
Can you offer any further tips? I am so grateful for any information you can provide!
