X-Cart say it's a server issue and they can't help any more without paid support.
I'm not paying another $99 for them to look at this, when it's never worked and I'm on an un-modified cart. It should work. Basically they won't support unless they host as well.
I asked them to explain what the settings should be and they can't without the fee.
Starting to think now is the time to drop x-cart altogether.
e reason why the feed is generated incorrectly (with wrong encryption) is connected to the server configuration for specific tables or database. Since you are not hosted with us, we are not able to check server configuration. Our engineers can investigate the issue in frames of Paid Support service for $99 and provide you with the details of what should be changed on the server-side. If it would be possible to fix it by accessing store files, they will fix it.
As an alternative solution, I would recommend considering our hosting service. In this case, we can guarantee the proper server configuration and update it to the latest PHP and MySQL versions. With the "Enhanced" hosting plan, that includes Support Subscription, we will proceed with the full store performance check and implement all the needed changes to run the store with the best speed and quality rates.
You can compare our plans here: https://www.x-cart.com/hosting.html
Please, let me know if you are interested and I will provide you with further details of our hosting advantages.
