Firstly thank you for an amazing productivity suite.
I have a reasonably fresh install of GroupOffice on an Ubuntu 14.04 LTS server (64-bit). The installation followed the 'Debian or Ubuntu Complete Mailserver Solution' steps.
Other information: Client browser Chrome 43.0.2357.81 m, Java 1.8.0_45-b15, Windows 8.1.
Everything is working fine except for the JUpload applet which is failing with a ClassNotFound exception for class wjhk.jupload2.JUploadApplet. I have Googled other help on this problem but none of the suggested solutions has worked.
The .jar file is present in the subfolder ./go/vendor/jupload/wjhk.jupload.jar. Note though that there is no '2' in the file name.
The URL in the window that is trying to load the applet is similar to the following:
https://mydomain:1234/groupoffice/index ... =sometoken
There is no subfolder 'jupload' in ./modules/files. I tried to create a symbolic link to ./go/vender/jupload but this had not effect.
Any help is very much appreciated.
