Which browser are you using? My guess would be Firefox 35. Please see the announcement on the forum. This is a hot topic and the announcement may provide you with the answer.
Looking at your screenshot, it looks like a browser issue to me. Where’s the help located? Web server or local drive?
Help is on my local drive...
The default browser as shown in the image is IE11. I attempted to "View with..." on Chrome - it tries, but just flickers and nothing opens, then I tried the same with Firefox just to see what would happen and it didn't even open and try to display the help.. :-(
ok.. i thought that was only with firefox.. i will look now.
ok.. so i changed the whutils file as noted for RH10...
the good news is that I can now see the TOC and INDEX in Firefox... but i still cannot see it in IE and i can't even get the help to open in Chrome.
There’s more fixes out there – the FF35 one was just the latest – see Willam’s site for a summary of all the hotfixes out there
i THINK I GOT IT FINALLY! I had updated all the patches I had seen awhile ago.. this must have been one i missed.. THANKS SO MUCH for your patience!
I've never had to work with all the workaround and patches before.
Well, I think this month is the first I can recall where we have somewhat of a "perfect storm" with browser updates breaking things. Adobe isn't the quickest when it comes to pushing out a service release to address things.
Thank the RoboGods for people like Willam that are able to identify exactly what needs to be changed, make those changes and share with the rest of us!
