Try old sphinx-rtd-theme ver: 1.0.0 back to 0.5.2

[Condo-Colin]

0.5.2 was the last known good version of sphinx-rtd-theme to work with our menu system.
Using 1.0.0 kills menu icons, and menu is not visible on mobile.
Maybe changing this back in docs.yml might fix the issue!

mobile didn't even cross my mind to check...

After looking I can see the top navigation bar problem on mobile, and have reported it.

I don't the icons problem though.

[Condo-Colin]

Thanks CJ! That's good.
So is the mobile menu still functional then, but just white/invisible??
The issue with the icons was, the first/last time it happened, the little expand/collapse [+] [--] icons on the desktop page menu also disappeared.

With the icons I wonder (hope) if this time your browser was caching the old theme.css and it might have been fixed by pressing Ctrl-F5 (or equivalent for forcing a reload of everything).

I'm glad you found and fixed both problems before the 4.0 release!

[Condo-Colin]

OK!
No, it was noticed after the release, so hopefully not too many people got lost looking for info.
You should join our Discord so you can be part of our documentation convos about our website formatting questions etc!
Cheers.
