Ticketing plugin PayPal payment options ‘greyed out’

We are using the wordpress events and ticketing plugin and yesterday we found that most browsers are now having an issue where when you get the to purchase/payment page for PayPal the page is ‘greyed out’ and all the payment options are inaccessible. Only Safari seems to work properly as did all the other browsers until recently. This is a significant issue for us, which if we cannot get help with soon will force us to move to some other plugins for events/ticketing.

Is there anything we can do to restore normal performance?

Thanks, Andrew
