What does this error mean?

Error - you are in Read Only mode. Any changes won’t be saved.

Glide gives me heart attack sometimes.

Saw this yesterday! Edit: Just happened again

I’m curious, when and where did you see this? When using the Glide builder or when using you Glide app? By any chance might this have happened when you lost your internet connection?

Data Editor : While editing the data it goes blank and then when refreshed this message occurs.

If internet connection was lost, how can this page be displayed? It should not be , No?

Most of the editor interface is cached locally and syncs with the glide server. Otherwise it would be incredibly slow if you had to wait for page refreshes every time you clicked on something.
