Edit Domain Price (Domains/TLDS) and Browse Extensions by Category

[ahwaznoname]

Hi,

We used to create two currencies to pay. But now we want to delete one of them.
When we try to delete, it gives us a warning message that this currency is in use.
We have removed this currency from the products. But we have not removed from the domains. This is definitely the reason for the above error.

The question is
1. We want to remove the second currency from the list of all domains, but our list of domains is high and we can not delete them one by one, and how can we remove this currency from all the domains in our list together? ?

 

2. We want to edit and delete the number of categories seen below. How should this be done?

3. How can we delete and add domains in each category?
