Element IDs Are Not Unique
How to fix:
This error appears the most when creating accordions. Make sure every set of panel IDs are unique. Meaning every accordion tab should have a unique set of panels.
1. In the edit view enter the Source Code pane.
2. Within the source code search the identical panel ID sets. In this example as mentioned in the error, there are two identical sets of "panel2a" used for two different tabs causing the error.
3. The set of IDs should be identical for every tab. For the third tab, I will be renaming "panel2a" to "panel3a"
The error has been corrected.
Element IDs Are Not Unique within Kaltura Video
When having many Kaltura video embeds the element IDs are not unique error will display. This is because the id="kaltura_player" is present within the video embed multiple times within the page.
Removing id="kaltura_player" from every video embed will remove the error.
