Hi there Robert,
Thanks for getting in touch with us and sorry to hear about this issue. Let’s find out what’s happening under the hood.
From what you are describing I understand this was working just fine, until you got the notice that the Facebook token expired, right? In the meantime have you changed your site domain or moved the files into a a different directory or sub-directory or any change like this?
If you go to ‘WP-Admin > Events > Setting > APIs’, do you see the option to ‘Disconnect’ the Facebook API? If so can you please click on that and re-try one you are disconnected? Also, when the new page opens to make this connection, does it never load at first or does it load and then when you click ‘Log into Facebook’ it keeps hanging?
One last thing, can you please send me the full URL of the new window in which the authorization is hanging (in a private reply)?
Thanks,
Nico
