 * This plugin was working fine for years. Now it’s generating an error on frontend
   which is blocking other payment methods:
   Uncaught ReferenceError: Square is not
   defined

 * Hi [@mike156](https://wordpress.org/support/users/mike156/),
 * Thanks for your question.
 * As this challenge is preventing sales at checkout, the Afterpay team would advise
   disabling the plugin immediately, if you have not already done so. Next, please
   consider taking a backup of the site (database and files), then rolling back 
   to the previous version of the plugin (currently v3.5.5).
 * The team would like to assist in getting the latest version running correctly.
   To facilitate this, please submit a support request including a link to this 
   post using the following web form: [https://afterpay.formstack.com/forms/global_merchant_technical_support](https://afterpay.formstack.com/forms/global_merchant_technical_support)
 * A member of the team will then reach out to you within 1 business day.
 * Thank you.
