I see a few posts indicating I might erase an old key and type in a new one. But this is not possible. The upper field showing the lifetime license key is in green and is not an editable field. There is an edit field below that to enter add a license key. But the key shown when I log into your site and what show in the green text field on my site do not match. What might I do to fix this?
You can try to temporarily deactivate all your pugins except Toolset Types and Page Builder by SiteOrigin, and see if it helps.
Kind Regards, Roman.
