Hi, thanks i will try, but i have to set this by login to the whole server with ssh? or to the site with the issue? because i am not sure that is possible anymore with Cloudflare that change the ip of that website so that i can manage to ssh to that website.
the thing is that i did not set that rule! i guess some plugin did it, and on the uninstallation stuck without deleting it! Anyway, that may help other people with the same issue. Thanks for your help.
