Hope I can get some help. It seems the Paypal Express checkout is broken on a Magento store. Anytime you click on "Checkout with Paypal Express" it just reloads the shopping cart page, doesn't go to paypal's checkout like it should. And another strange thing I notice, when I go into System>Configuration>Payment Methods the "Configure" button for "Paypal Express" is grayed out and not clickable. The only way I can make it clickable is if I inspect the HTML code and change "disabled" to "enabled" in the button element.
Thanks in advance
