Xibo 1.7.4 client not showing date and time on display

I have a xibo client 1.7.4 on ubuntu.When I make a layout to display data and time on the display, it does not show anything,the screen remains blank.
When I check the log,it says the following

<?xml version="1.0" ?>

** **
** <Fault SOAP-ENV:Client: Error cannot find parameter>**
** **
** **
** **
** .SubmitLog**
** 3542**
** **

Also on the terminal these messages are being displayed

Thanks in advance

Looks like you are missing “libvdpau-va-gl”. Please install that via the terminal with “sudo apt-get install libvdpau-va-gl” or simular depending on your version of Ubuntu. I would also suggest upgrading to the last stable release of the 1.7.X series, 1.7.9, or maybe even the 1.8 series.

Thanks Colin.I tried the same but it didnt work for me

Then I would then guess a permissions issue. Maybe the Web Server does not have the correct access to the files for Xibo?

Other than that @Peter, might have some insight on this.
