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.
i did this to the root, it indeed affected the page that i had the problem only, i see as a result success. but the back end is a mess, it is cached still.
Go do the Dashboard > Cache > Configuration and hit the Purge All button. Partial purges won’t help you here. Then visit your site in an incognito window to check if cached content is still there.
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.
