Acces forbidden for create product menu in backend

-- HikaShop version -- : 4.2.2
-- Joomla version -- : 3.9.15
-- PHP version -- : 7.3.15
-- Browser(s) name and version -- : all browsers
-- Error-message(debug-mod must be tuned on) -- : Standard error message: Access forbidden

Hi,

In the backend I created a menu for webmasters to allow them to modify and add products. When they use the menu-item with menu-item-type "product listing" they are allowed to add a product, but when they use the menu-item with menu-item-type "create product" they get the message "access forbidden".
So it looks like the rights to create a product assigned, but only via the product listing it is allowed to add a product, not via the "create product" menu-item-type

Thanks,
Peter

The problem is solved by installing version 4.2.3.
(PS: I did not notice this update because there was no Joomla-update message for this version)

Thanks,
Peter
