It is evident that the developers have not prepared their website for a promo on AppSumo, you have no reference to your limits, the offer, absolutely nothing. You simply put your email in the activation, it redirects you to a panel and that's it, no reference to AppSumo, I wouldn't mind as a general rule but:

First I tried with a website and it turns out that my hosting provider blocked its IP, understandable, I proceed to request that they whitelist it and it doesn't work, I understand that is normal, try to delete the cache and nothing, try to search in their knowledge base for information about deleting the website to add it back and nothing either, they only have instructions to delete the whole account.

Write to support who write you every 24 hours (pretty standard) the problem and with it the frustration, is that they DO NOT READ the tickets, I waited 24 hours for them to explain me, as a solution to my problem of the website not working, where I suggested to delete it and create it again, a link where they explain me where to delete my whole account, not the website as I was asking for.

I wrote to them explaining that I wanted to delete only this site (as I said when I opened the ticket) and their answer was "Its for whole account", does this make any kind of sense?

I let this website pass as a lost case and proceeded to add a new one, because now the system tells me that I don't have the robots.txt file, when obviously I have it. Anyway, my congratulations to all the people that it has worked for them, I was not so lucky. Good luck to the people who have not bought the unlimited websites plan, because apparently there is no option on the face of the earth where you can delete one of the websites.
