I don't know what happened but I'm having a serious issue and I'm freaking due the fact it is one of the most important step of my shop.
The bug only occur while using Firefox.
WP Version 3.5.2
Woocommerce V. 2.0.20
Customers can register without problem by simply adding an email and pw.
When they're going in their account to edit the Billing and Shipping addresses, all the forms are there but when they click the save button, they are automatically SIGNED OUT!
SIGNED OUT and the info are not saved at all!
Any help will be appreciated!
I tried deactivating all my FF and WP plugins! No success!
Actually due a theme incompatibility, I can't update the WP and Woocommerce version.
