Using D7 civiCRM 4.7.22. The "save" button is greyed out in the back end new contribution form (and the "confirm contribution" button in online forms) after upgrade to 4.7.22. This happens as soon as I select a payment method other than default in the back end. e.g. the default is "check", if I select "cash" then the save button is greyed out. This also happens in the online form (no payment method is available for selection, but if the default isn't set as "credit card" then the "confirm contribution" button is greyed out).
This was all working as expected in 4.6 before upgrade.
Thanks for your thoughts!
