Hi Jason,
I have an Update: User preferences have been reset, so they should not contribute to any problems. I also deleted the configuration folder for Dreamweaver, just to be sure.
I now have another error message, this one on the detail page. When I click "add to cart", products are added but the cart page is not loaded.
This is the error code:
Warning: Cannot modify header information - headers already sent by (output started at /var/www/html/www.ourshop.eu/web/detail.php:357) in /var/www/html/www.ourshop.eu/web/detail.php on line 370

Regarding the original error message: I haven't had a chance to get in contact with our provider, but UE does work. Confirmation Emails are being sent.
To troubleshoot the site, I need the site to work on my local testing server, but as soon as I confirm an order, the site is completely stuck. It won't load the success page, go back or load any other link. When I try to open any other page, it doesn't load (the loading circle keeps spinning) and stays white. That problem persists until I restart the browser. Then again everything works up to the point of confirming the order.
Jason, could you look into this please?
