TheWormsUnited kamalo You must use the correct entry, that seems to me that you logged out and the address has changed since you changed it on the settings area. Do you remember the address you input under your Settings?
awaludin yes use correct entry. for example the above error was produced by http://yourdomainorip:8888/login . You have to your http://yourdomainorip:8888/panel or any other entry that is assigned by aapanel installation or any entry you have changed from settings.
kamalo hi again, I am using the aaPanel demo website, and I didn't changed any thing, just browsing the features available! regards
