I can not see the table of contents..
can not see the table of contents in Firefox and IE9, but if crome, why?
Can you clarify the problem and confirm what version of HelpStudio you are using. Thanks.
It looks as though your web output contains invalid characters in the .xml files that HelpStudio generates to support the navigation pane (specifically in the "Search" phrase). I suspect this is due to localization of the phrase "Search" in this project. I would recommend trying to set your encoding in the Build Profile editor to "Unicode (UTF8)" for web outputs - that should avoid encoding problems such as this. If that doesn't cure the problem, please drop support@innovasys.com an email with a copy of your project so that we can assist further.
