I am currently investigating an intermittent payment issue where some credit cards will work, others do not. I’m pretty sure this has something to do with how my site communicates with Square and it’s probably a problem with a plugin. If you sign up for a class and try to pay by a credit card and it fails with a “BAD_REQUEST: INTENT_MISMATCH” error, then please contact me so we can work out an alternate form of payment.
UPDATE 2/25/20: I downgraded the plugin to a previous version, so hopefully the problem is gone. I won’t upgrade the plugin again till they find the cause. If you still have problems with this PLEASE CONTACT ME!
I will post an update here when I find out more, thanks for your patience everyone!
