Internal Error 10001

can anyone please help?

Our website has suddenly been subject to a number of failed transactions starting at 8pm this evening (no one is working on the website at this time at night).

The website has been trading for 6 years & we have never experienced anything like this

All have internal error 10001.

an example is below:
