Grid view cover not displaying on mojo

I have been using mojo for a while now and all was good until I updated my Wd live smp to the latest firmware. No when I create covers on thumbgen they will display in all the other view except the grid view. All the old ones I generated do anything I create new will not.

any ideas where I’m going wrong?

The theme might be incompatible, try rolling back to the previous version and check if the problem continues. Check the link below for the steps.

Well, if you have the SMP you are in the wrong forum anyway.  The thread for the MOJO for the SMP is here:

If you downloaded the theme from this forum then you downloaded the wrong theme, as it’s for a specific FW on the HUB.  You need to download the theme from the thread I pointed to above.
