404 Error on Mobile Page after Upgrade to iPrint 23.4 appliance

Hello,

after upgrading our appliance to 23.4 I get 404 error when accessing the "Mobile" tab on the appliance management page.

This error also prevents other tabs and even the printers in the ipp portal to load.

Mobile tab:

Fehler:  DataModelException

Nachricht:   Failed : HTTP error code : 404

Other tabs:

com.novell.admin.common.server.rpc.beans.RpcException: com.google.gwt.user.server.rpc.UnexpectedException: Service method 'public abstract com.novell.admin.iprint.server.web.beans.MobilePrinterList com.novell.admin.iprint.client.services.IprintRpcService.getPrintersAndEmailSettingInfo() throws com.novell.admin.common.server.rpc.beans.RpcException' threw an unexpected exception: com.novell.admin.common.datamodel.beans.DataModelException: Failed : HTTP error code : 404
	at com.novel


I couldn't find anything related in the KB yet. Any idea if it is possible to simply disable the mobile portion of iPrint since we don't even use it?
Or should I just open a case?

Edit:

Checking the mobile.log (/var/opt/novell/log/iprintmobile/iprint_mobile0.log) I found this entry, but I don't know if it is related since the last entry is from the time when the upgrade from 5 to 23.4 was done:

Caused by: java.lang.IllegalStateException: java.io.FileNotFoundException: /var/opt/novell/iprint-tomcat/webapps/iprint/WEB-INF/lib/activation-1.1.jar (No such file or directory)


Thanks in advance

Regards,
