An error has occurred. 0 Undefined constant "K2_JVERSION"

Just downloaded jux news wall for joomla 4 and get this error when trying to open it:

An error has occurred.
0 Undefined constant "K2_JVERSION"

lapeercountyconcertchoir.com/administrat...out=edit&client_id=0
lapeercountyconcertchoir.com/

More info - I took the same download and installed it on another site just fine.

But on this site I get this error when debug is turned on - it keeps mentioning k2 - but I do not use it.:

Thank you very much!!!

I have an article with a module in it that opens just fine normally. ( lapeercountyconcertchoir.com/index.php/h...-06-12-13-57-06.html -- Rapi music player is the module)

If you go to this link : lapeercountyconcertchoir.com/index.php/h...-06-09-16-46-35.html -- and click on "Christmas Handels Messiah 2019) the same file opens but the module does not) ({loadmoduleid 585})

Can I not put a module in a file for Jux News to open? Also "View more" does not work - there are 12 articles.

Thank you - some improvement
Found that - MODULES NEED TO BE IN DEBUG POSITION - FIXED IT

But now "View More" does not work and the program does not show all the files in "program' or "recordings" folders
Concert programs - 11 , Concert recordings - 6

Also how can I get it to sort by date - Changing file name - alias - creation date?
Thank you
