IWP web viewers stopped working. Browser says "cancelled opening the page"
Operating system version
Mac OSX Server 10.6.8
Description of the issue
Any tips would be appreciated. I added a few layouts to an otherwise stable online database and all of a sudden the web views stopped working across the board. No changes were made to the system (or ports), but web viewers no longer work on line. I have created mock pages with basic viewerss and they will not work.
I have reinstated previous version (working 2 days ago) and these no longer display the viewers.
Steps to reproduce the problem
View any page with a web viewer on line.
Exact text of any error message(s) that appear
