timelines no longer displaying

Hi,

I use the timeline block on several pages on my website. Yesterday I noticed that the timelines are no longer displaying on any of the pages where the timeline block is included. Not sure when this behaviour started. I tried to remove and re-install the plugin but nothing changed.

The plugin I installed is Timeline Block. All the pages I have under “Countries” have a timeline block.

Thank you in advance for your support!
