Hi and thank you for the new thread here.
Is this consistently happening for you, or has it only been maybe once or twice? Also just to be certain, you’ve managed to successfully disconnect, it’s just the re-connecting with a new user/account that’s failing?
Sounds like it may be a 403 forbidden
error going on
I happens every time I try to disconnect the current user.
I tried, on a staging site, disabling all plugins except this one and it’s still getting the error.
I tried deleting the plugin and re-installing it.
It’s now disconnected but when I connect I get:
Error: The id token is invalid

Hmm. Odd that it’s giving you a URL like that one, since API changes weren’t supposed to be affecting our official plugin at first, while we do some ongoing work to get everything migrated over.
Forgive me, but just for some extra assurance, it’s this screen that’s failing you, correct?

Found at /wp-admin/edit.php?post_type=ctct_forms&page=ctct_options_connect
Yes, that’s the screen that I get the: There has been a critical error on this website. Please check your site admin email inbox for instructions.
