check out will not go to paypal
My site used to check out via paypal. Now it does not. I followed the instructions from your support area making sure everything was checked that needed to be checked and so forth. However, it will not allow a guest to check out. It will not logout a visitor. It will not go to paypal to complete the payment. I am stumped. I do not know why it worked and now it won't work. Please help me.
