Here is a screenshot of the message I received from tech support this morning:

Thank you for contacting support. I'm truly sorry to learn that you are having these issues with your website. However upon review of this information it appears that this is a coding issue and some of the settings in your files are not configured correctly in the config.php and other files. This would have to be updated. You would need to have a developer look into this for you, or you can try the customer community, more information can be found below:

While we in the Support Department would not be able to assist you with that, you are welcome to contact our Customer Community Team for assistance. They are available Monday through Friday between the hours of 8 AM and 9 PM. They do answer questions within 60 minutes when you post in our Support Forum

PLEASE! Can someone help me to fix this?????????
