We have a webshop using Joomla/Virtuemart system with their latest versions. It seems when someone places an order and wants to pay through PayPal the following error message gets displayed upon using the Firefox browser: "Things don't appear to be working at the moment. Please try again later." It seems this problem does not appear when using Chrome or Edge browsers. Can you please look into this problem and let me know the solution. Thanks and looking forward to hearing from you soon.
