Timeline just died
My timeline suddenly stopped displaying. In its place I now see a white box stating: Missing mandatory data - not able to draw the timeline. Please open this H5P in the editor, and make the necessary changes. Yes, I worked on timeline recently and could have inadvertently elbowed the keyboard--but I have had this timeline for years and nothing like this has ever happened.
Troubleshooting: Copied timeline, created a new timeline, pasted, got the same error.
The timeline is displayed at https://hebrewlion.com/learn.
As always, thank you for your assistance.
(ps, any word on when BCE/CE notations (replacing BC/AD) are due out? Requested in 05/2021)
(ps, any word on when an option to add 'circa' beside date is due out? Requested in 05/2021)
