Hello Robert,

On admin_events_tab.tpl line 130 :
if( _holidays == null || _holidays.length == 0 ) return;

> The problem is that, when we don't ues the Holidays stuff, the ajax function
gives a blank document with one line, which causes the JS to consider it as not
null or empty.


I suggest:
if( _holidays.trim() == null || _holidays.trim().length == 0 ) return;

And it works now

But maybe the best way to solve this is to clean the ajax function to not return
a single line break

Thank you
