I installed GeoServer on Ubuntu Linux 14.04 using the OS-independent binary that comes with Jetty. I am running it using the bin/startup.sh file. I am trying to create an ImageMosaic. When I try, I get this error message in the browser console:
ReferenceError: Wicket is not defined
I also get odd error messages in the console here and there, complaining about not finding JQuery - and yet, according to Firebug, the JQuery JS and CSS files get found and download OK.
