Breadcrumbs stopped displaying

[Dinnit]

Can anyone think of something I'm missing??

I've had breadcrumbs displaying for years above all topics using the Tri-pane format. Now they've suddenly stopped appearing and all that displays is the "You are here:" text with nothing after it
The Breadcrumbs proxy is in the Master page, the topics are all linked in the TOC, the count is still at 3, the font is an off-white on a dark background, display is set to block, the only condition set are for including in online output.

I can't think of anything else to check.

When did it stop working? Was it just after moving to Flare 2017r2?

If you are using 2017r2, then MadCap changed how breadcrumbs are generated - instead of being added during build, they're now added at runtime using a script.
So if it's not working with 2017r2, my guess is that MadCap's script isn't running properly for whatever reason. Perhaps try opening the help in different browsers, or on different PCs.

Could well have been. I'm working on a Top Nav version so haven't had my full attention on the existing and haven't really made any changes to it.

Normally use FF, but just tested in Chrome, Edge and Safari and all give the same result. I'm working remotely so I'll get the tech section to have a look at the build process internally once the office opens.

Many thanks. If I find anything that might be useful for anyone I'll post back.

Sorted - it appears to be an issue just with my Windows 10 PC. Everyone else can see the breadcrumbs properly. I can't say it surprises me - had nothing but random problems with this PC since Windows 10 was installed.
