UPDATE: This is resolved. It turned out to be a server issue. Our database server provider had experienced network interruption. When they rebooted the server, the website came right back up. Thanks all, so much!! You rock.
Hello, I have a FMP web application that's been up and running for over a year.
Today, I received notice that it was down, and when I go to the website, all I see is a blank page and the following error message:
Error: XML error: Not well-formed (invalid token) at line 1
I'm not aware that anyone on our team has made any changes to the PHP code or the FMP server configuration, but obviously something in the environment has changed.
Tips on troubleshooting this? I don't know where to start.
