We recently upgraded to RoboHelp 2015, but it seems that many some of our users are running into a problem when search our published Webhelp system using IE 11: They will search a term and the results field will display: "Error: Failed to load xml file". This is happening sporadically. Some users can refresh their screen and the search problems will go away. For others it persists. For some people the problem will go away when we republish the system, only to find someone else with the problem the next day. I can't seem to replicate it on my machine.
Any ideas what it might be? I've updated to the latest version (12.0.3.428) and this problem does not exist in Chrome.
Thanks,
Greg
