Can not create product

Hiii Sandeep, I need urgently help, have the site finally ready, now i must see that i can not add products as vendor. I logged in with an vendor account, all permissions inside profile are given (submit products) in WCMP and in Users profile. Using the shop theme, ultimate member plugin, front end WP, woocommerce booster and of course woocommerce. On “add aricle” i got redirected to the shop page (in my case that is frontpage). thanks so much for helping all the times
