“My DatePicker isn’t working, so I can’t enter or edit events?!
In most cases where this happens, it is a result of your theme not using the internal WordPress jQuery libraries, resulting in an error when we try to use them. Your theme should be using the same version of jQuery as WordPress. Read Marcus’ post about themes overriding the default jQuery libraries for more information on fixing your theme. http://msyk.es/blog/prevent-jquery-wordpress-theme/”
Is there any hope, or do I have to just do trial and error with a number of event plugins to find one that works?
