Waiting for your reply
Seems like you have restricted access of instructor to wp-admin by some other means using a third party plugin or custom code .
Try to remove that code (if added) or deactivating third party plugin in your site .
Still issues does not resolves then please share your site url , admin credentials and valid ftp credentials in private reply to check this issue at your end .
Well we checked your vimeo token at our end .
the response was fine at localhost :
but this does shows some error with same vimeo token at your site .
You would need to contact vimeo support about the error code 8003 ,
check if they might have blocked the site or something related to domain or country .
