But the files are viewable on a server (we've tried two servers). Any ideas?

OK - further update - adding the "--allow-file-access-from-files" flag to the Chrome shortcut does solve the issue. So it's definitely some change that Chrome has made that's short-circuiting the fix that Adobe made to RH to get around this before.

You'll have to give us some more detail to have a chance of helping you. What do you mean by "refresh loop"?

The page does not load. It's blank and the window just keeps flickering.

Are you generating WebHelp? if so, does the same happen on different browsers, different PCs, etc. Also is it the whole frame that doesn't load or just the topic area.

Try generating the same output from one of the sample projects and see if this works. If this is OK, try generating your project to a different location; preferably on a local hard drive.

@Colum - I'm seeing the same behaviour using Chrome version 30.0.1599.69 on a locally generated WebHelp test done using the sample Salesbuilder project. I've checked the settings to see if JavaScript is enabled & it is. This used to work just a little while ago, but some update in Chrome has busted this again it seems. I've filed a bug report with Adobe this morning about it.

Update - it also fails when located on a LAN server too. I'll test next with the "local file access" flag to see if it's a "security" issue ;>)

This did not solve my issue.  I am running into the same issue but it is stemming from viewing a project generated from MadCap Flare.  Added the tag to the Chrome shortcut but am still seeing a blank page.  Any other solutions found this far?

@wacobear - not sure I follow...You're testing WebHelp produced by Flare (not RH) and asking about it in a RH forum? If that's the case, then it seems to confirm my theory that some change has been made to Chrome to tighten things up again. If that's not the case, you need to explain more about this project and what sort of results you're seeing and what you've tried.

Which version of Chrome did you see this behaviour? Do you have any custom scripts running? Any plugins?

I've not seen this Chrome issue on RH10 before and since the WebHelp rewrite for Chrome, I'm surprised the issue occurs.

Willam

@Willam - I'm running Chrome version 30.0.1599.69 - I don't think I've got any plugins installed (Chrome's not my browser of choice; I just have it around to test with). Yes, I thought this issue was licked too when Adobe came out with a fix. Give a whirl yourself & see if it's behaving the same way when trying to run the Salesbuilder sample as WebHelp on a LAN or local drive.

Aargh, I just looked with the same version (30.0.1599.69) and I have the same issue. Be sure to report this as a bug to Adobe (https://www.adobe.com/cfusion/mmform/index.cfm?name=wishform) It seems Chrome has made the cross frame communication even stricter with this patch.

I have found a dirty fix that may help. It seems to work fine, I gave WebHelp a spin, but I haven't thoroughly tested it. I hope Adobe can come up with a nice fix.

Please note: this fix is extremely dirty and should only be used as a workaround. I cannot guarantee that your WebHelp will work correctly!

Saying that, here's a fix:

1. Open whproxy.js with a text editor.

2. Find the function getStubPage.

3. Replace the function with the following function:

function getStubPage() {

    if (!gbInited) {

        if (msgHandlerProxy.checkChromeLocal()) {

                              try {

                                        var oWnd = top.frames['ContentFrame'];

                              } catch(e) {

                                        var oWnd = top;

                              }

            if (typeof (oWnd) != 'undefined' && oWnd != null)

                gWndStubPage = oWnd;

            else

                gWndStubPage = top;

            if (gWndStubPage == this)

                gWndStubPage = null;

        }

        else

            gWndStubPage = getStubPage_inter(window);

        gbInited = true;

    }

    return gWndStubPage;

}

Greet,

Willam

Can someone please explain how to "add the "--allow-file-access-from-files" flag to the Chrome shortcut"? Thanks!

See Item 3 at http://www.grainge.org/pages/snippets/snippets.htm#browsers.

It is something the user has to do in their shortcut to Chrome. Their System Admin might not like the idea so beware.

Make a copy of your Chrome shortcut and right-click on the copy to edit the Properties. Add the –allow-file-access-from-files text to the end of the target path – it will read something like:

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --allow-file-access-from-files

Hi Everyone,

Does anyone have any more news on this?

I was expecting major fallout and possible news of an emergency Rh release to deal with this, but it all seems to have gone rather quiet.

Many thanks in advance.

Cheers,

Andy

How about on the Mac OS X?

There seems to be still a problem when replaced with new "whproxy.js".

The left pane is not displayed in Chrome (version 31) on Mac OS X.

Chrome on a Mac – hmm. Never dealt with that, ever – if the RH fix is still busted in that scenario, you’d better file a bug report with Adobe.
