Solved:
Ok, it is like I thought and the version 2.7 won’t run on WP 4.5. (of course, it’s not supposed to, my bad)
So, I did the downgrade to WP 4.4.2 and all is well in jPlayer land.
Seriously, can’t live without this gem of a plug.
Should become part of WP installs; so far no equal!!!!
Thanks, dev!
