"An error occured during creating the thumbnail."

Hey there,

The widget 2 x4 product grid on the quickstart for http://www.mistermicawber.co displays one thumbnail but the others show "An error occured during creating the thumbnail.", any help for this? I've tried reuploading the images, replacing the media and even upgrading to a better hosting package.

There's currently a maintenance page up so you'll need account login information to get past it which I can supply in private if necessary.

Thanks in advance,
Hamual

Hi,
Could you please provide me with a back-end access via PM so that I may analyze it?
