SOLVED: I had turned on the WP_DEBUG in the wp-config.php file.
Changing this to false eliminated the error on screen.
“also placed images on pages using the Avia Layout. When I migrated the site using BackupBuddy, all the images reference the images subdirectory. I had to manually relink all images on the site.”
It is not just the layer slider it is ALL the images. They all reference the old subdirectory even though the images were moved by BackupBuddy.
I installed the theme on another site and had the same problem with the search box not appearing correctly – same Windows 8 machine.
