I recently installed the ko-fi button because it was suggested by the kofi company but because it redirects people to a blank page and ko-fi button, I decided to uninstall it.
The page that needs login, apparently because my IP was blocked from my own website (My sister was trying to log on multiple times that resulted to being blocked), so as a security measure, the server made those log in. But they were fast though, I just slept and I can access my own website. They said that it needs at least a week.
Sorry for the inconvenience.
