Hi,
I'm using woocommerce for downloadable files. and my paymentgetway is:
http://www.mediafire.com/?gsvl87g917pg4bi
Unfortunately, the order does NOT automatically change from PENDING to PROCESSING, as it should as described in the WooCommerce documentation. This is a huge problem, because when the buyer logs into the "My Account" page, he/she can still see the "Pay" button for an already paid order - which is very confusing.
how can i resolved this? is there any function to make all successful payment to "complete" or "proccecing" automatically? or problem comes from by my paymentgetway?
