In a website running Joomla, eventlist component has been installed working perfectly. We required custom fields for the comonent, so installed the viperwebsites custom fields hack, known to work well in many applications. All installs ok, categories and venues can be updated, but when saving the event itself, no connection is made with the database and the page remnains static, nothing saved.
In firebug, the following error is seen (no error shows in the Joomla screen)
[url removed, login to view] is undefined
[Break On This Error] alert("ENDDATE WRONG");
index....=event# (line 585
This regardless of enddate settings in the back end.
