Collaborator users homepage is not loading

Collaborator user's home page is not loading.   It simply says loading and never loads.    We are seeing this in the error log:

    Try to refresh the server instance by following the steps below:

    1. Stop the "ccollab-server" daemon/service.
    2. Delete all of the files and folders in the "<INSTALL_DIR>\tomcat\webapps" directory.
    3. Delete all of the files and folders in the "<INSTALL_DIR>\tomcat\work" directory.
    4. Make sure you only have one .xml file (ROOT.xml) in the "<INSTALL_DIR>\tomcat\conf\Catalina\localhost" directory. (Please note - all files with a ".bak" extension may remain.)
    5. Start the "ccollab-server" daemon/service. 

     

    As a result, Collaborator will load all needed jar files from scratch. 

     

    If the issue still persists, try to enable the debugging session in the WebUI and check the error details:
