Direct vendor form doesn't work 404 error

I have done everything required in the guide (How to add a vendor registration form - HivePress Help Center) to add the direct form for vendors. However, I want them to have attributes that are specifically for sellers such as site link, vat number etc…

I have added as requested the “become a vendor” label in the menu, but it gives back 404 error.
what can I do?

Hi,

Please disable third-party plugins and customizations (if there are any) and check if this issue persists. If you use a caching plugin, make sure that caching is disabled for logged-in users. Also, please refresh permalinks: How to refresh WordPress permalinks - HivePress Help Center

​I hope this is helpful to you.
