I even tried to restore all files in server side. But, it’s still can’t solve the problem.
It’s really desperate…….
Hi,
The Login/Register link on your website might be added by the theme as the CSS for it is pointing to the theme files. Please check the theme settings related to menu or header to see if there is any area to enable/disable such links.
Your theme has two or more menu areas, at least a right and left header menu, maybe more. In the Manage Locations tab under Appearance>Menus determine which menu is assigned to the right header menu (the menu location may be labeled something else). I suspect you may have been editing the wrong menu.
Back on the Edit Menus tab, select that assigned menu just below the tabs and remove the log in/register menu item. Save the change.
If you did all that and the item persists, perhaps you have caching active that needs to be flushed so that the revised version will be served.
