Checkout Page Error "internal Error server"

I have opencart 3.0.3.7 installed.
I am using Square to sync with our physical store inventory.
I am using journal3 but I do not believe my issues are Journal related. (Correct me if I am wrong, but do not discard my question simply because I am using Journal)
My site went live and everything was working.
I purchased an item with no issues.
Now the checkout page gave me an error listed twice in the same warning box.

internal error server
internal error server

There is nothing in the error logs found at Admin>System>Maintenance>Error Logs
I searched the forum and cannot find my Server error logs.
I am using Cpanel and I assume that the logs folder in my root directory is where i would find an error log. However, that folder is empty.

Any help is appreciated.
