I was directed to the announcement about Gantry 5.5 upgrades and step 4 advised going to the Gantry 5 Menu Editor to save each of my menus.
I honestly don't know where that is or how to do that.
I use one of two templates: Fluent and Ambrosia. I may still have a few sites on Stratos, but they're inactive. I don't think any of these are "RT" templates, so I think I'm okay there.
The only reference to a Menu Editor is the Menu item in the Particles tab - and I don't see how to save menu items there unless it's just a matter of disable - save - re-enable - save.
We have not yet released theme updates for any RT templates (which includes fluent and ambrosia) - so you should not have updated to g5.5 yet as your themes are not compatible yet - this is what the announcement states.
Nevertheless, to answer your question you go to gantry 5 admin and press the MENU button top right, the choose you menus from the drop down and press the SAVE button.
Regards, Mark.
