GuguguBear When I refresh the page, I can enter the forum. But many things are not right. For example, I enter the background. Try to modify a setting. When I click save. It will prompt an error, and the modified settings will not be saved.
GuguguBear So I tried to re-grant them the entire folder permissions to [755] Now I can save settings and modifications. But I am not sure if there will be other unknown issues.
