The background image issue seems to have resolved itself in subsequent updates of the template we designed.
But to add to our issues we are now getting modules, that are NOT assigned to anything, displaying weird background images at position hbmodulepositionnn
The background image in the modules appears to be the same one that we saw previously in the background. I'm suspecting it is some old image on our server that for whatever reason is interacting with the template,
I have kludged it by setting the hba module positions to none for now.
