I'm using the Wordpress Woocommerce plugin and the "Check out" page gets stuck after the form is submitted with the correct info and won't continue to a confirmation page.
NOTE: I'm using an Authorize.NET gateway with the recommended test Credit Card numbers and I received the confirmation email. Also, no JS errors!
Any ideas?!
Are you usingany other plugins, like pdf invoices?
I had this same problem which was caused bij some kind of language conflict. By switching Wordpress back to en_US in the wp-config file, the problem didnt occur anymore.
