Not sure why but I'm getting an Internal Server Error 500 when I try to alter and save any product description. This only seems to happen when I copy and rename or simply alter and save an existing product. I do not get the error when I simply create a new product. This occurred both before and after my update to 2.0.3.
Sound like this is an outstanding issue. Please submit a new ticket to EShop category to send me the super admin account to your site so I can help you to check and resolve the issue.
