Hi,
I've just updated (on a backup site, fortunately) from 3.6.4 to 3.6.7, and the logo and other background images have gone - it seems the files I uploaded to /wp-content/themes/atahualpa/images/ as per the instructions were removed by the update.
Is there a definitive list somewhere of what options / customisations have to be redone when upgrading? Seems a bit odd that it would remove them without saying...
Thanks,
David.
