So, just a quick post in case this happens to anyone else. Of note:

• I am using a very customized version of the Charcoal HTML5 responsive layout.
• I am using RoboHelp 2017.
• I am using Chrome 63.0.3239.108, 64-bit.

So, I noticed I couldn’t search in google chrome, though it worked fine in other browsers. Nothing on the interwebs, no hints. I could type in a search term, the suggested searches would populate just fine, but hit enter and nothing.

Long story short:

1. In Chrome, click the [more icon, three vertically stacked dots at the top right of the browser].
2.  Click Settings.
3. Scroll down, then click Advanced.
4. Click Content settings.
5. Click Cookies.
6. Deselect Block third-party cookies.

That oughtta do it.
