I have built many web-form sites which are processed by
CGI programs in perl on UNIX servers. Occasionally a user
reports getting the error dialog "No data found in document"
or just "No data found" when clicking on the Submit button.
Can anyone tell me what causes this? It only occurs occasionally and only to certain people. Is there a client
environment issue which usually causes this? I have also
experienced this myself occasionally when filling out web forms.
