The livetables get their content from json, fetched through an ajax call.
The best way I found to debug a broken livetable, is to use Firefox +
Firebug. In the console, when displaying the livetable page, you should see
the complex url used to retrieve json data (call to a page named
LiveTableResultsMacros).
Copy-Paste this url in another browser tab, and then you will be able to see
if :
- output is really empty,
- a velocity error is shown, meaning there is a problem with the part that
generates json. From the error you can start investigating.
