@arsenalemusica, thansk for sharing the images, that indeed helped us understand the issue better.
Now the issue you were facing with i.e. https://imgur.com/q8LYLNM, yes, this is not added any more in WCMp. As you are using theme’s documentation hence this scrrenshot of old version, I would recommed you to follow our documentation to install the plugin : https://wc-marketplace.com/knowledgebase/wcmp-setup-guide/.
Also as you can see, this section comes from WooCommerce, however this is also from older version of WooCommerce. Here is the doc of their current version : https://docs.woocommerce.com/document/configuring-woocommerce-settings/#section-15
Regarding WCMp, our plugin creates Two pages by default i.e. Vendor dashboard and Vendor Registration as you can see here : https://wc-marketplace.com/knowledgebase/installed-pages/
Hence in order to let user register as vendor they need to fill up our page Vendor Registration. For better understanding you may reffer to this link : https://wc-marketplace.com/knowledgebase/setting-vendor-registration-wcmp/
Regarding the issue i.e. My Shop missing, Stripe issue, can you please contact our team over forum (https://wc-marketplace.com/support-forum/), so they can inspect that in your site.
For the logout dropdown, it might be releated to theme conflitc. To resolve this, please add this code in the function.php of the current active theme
if(!defined('WCMP_UNLOAD_BOOTSTRAP_LIB')){
define('WCMP_UNLOAD_BOOTSTRAP_LIB', true);
}
Let us know if this fixed the dropdown issue.
