Hello.
Worth Joomla 4.0.3 + HikaMarket 4.0.0 + HikaShop 4.4.3

There are several bugs.
1) hikashop -> Registration form -> if I register with the parameter "User activation by yourself" (via the link in the activation letter):

    0 Class 'JError' not found

I downloaded the new version, and I see that part of it has been tweaked.
1) hikashop -> affiliate program:

3) How to register a seller? In the version for joomla 3 - there were 2 registrations: the 2nd made the buyer - the seller. Do you have this functionality? How to do it? (I'm not talking about the admin panel, but about the outer part of the site)

4) If it is important: upon user activation (after registration - a letter came - clicked on the link to activate the user) - an error related to "did not find JError" is issued, but it is eliminated if VirtueMart is installed.

2) I'm waiting.

3) In HikaMarket (Maybe HikaShop?) There is no "Registration" item, there is a "Seller page", which in its meaning hints at "registration" if "The one who is watching is not the seller". If yes - an error from point "2)"

4) Without VirtueMart

I see a partial fix.
Error: "2) hikamarket -> seller page" is still there.
Also the question: should the "hikamarket -> seller page" page "show the seller page" or offer registration as a "seller"? If "suggesting registration as a 'seller'" is incorrect, then where is the registration of the buyer as a seller?(from the outside, so that the person himself is registered as a seller, if he wants (not through the admin panel))

I am writing here because I think that the problem is not completely exhausted. If you are not right, sorry, and move it where you need it.
In general. Created page: hikashop -> Registration
A message is displayed from the variable "NO_CUSTOM_ENTRY_FIELDS_FOUND"
I go to: administrator -> hikashop -> "Display settings" -> "Additional fields"
I see a certain number of fields. I look: about 90% published. In the filter field I select: "Seller", I see: there are a bunch of fields, and almost all are "Published" and in the "Site" column there is a "tick" (they say it is displayed on the site).

Actually the question is: what is wrong? In the config, everything related to "Additional fields" is included.

Original(Message, RUS):

I reread www.hikashop.com/support/documentation/1...to_menu_registration and apologize for misleading. I wrote about the wrong page, but your answer was interesting to me (I read the article)

I'm interested in:
Constant (because my original is not in English): COM_HIKAMARKET_VENDORMARKET_FORM_VIEW_DEFAULT_TITLE
Technical link: /index.php?option=com_hikamarket&view=vendormarket&layout=form
In general. When I try to access this page, it redirects me to site.info/index.php
No error messages / any information.

Actually: how to debug?

I was buying an organization, I am just setting it up technically.
