Bad Request reponse to users.
The database is on a FileMaker 10 Advanced server and users access it using IWP, it now returns this message when users including the admininatrator navigate to a layout from the login page.
"Bad Request. The server could not process your request due to a missing cammand: "".
There is no escape from this message but to force close the browser using the task manager.
The database had been working well and no changes had been made to the file (as far as I know) when this error suddenly appeared. As administrator I am able to work on the database from a client and no errors present at that time. I suspect IWP but would very much appreciate help to resolve this problem.
