Can't Update This Collection (Code: 409)

Backlight 4, 5 & 6 Support

I’ve got hundreds of galleries uploaded through Lightroom whose formatting seems to have recently broken.

See sample below

When I try to “rePublish” the gallery, Lightroom gives me the following error
Can’t Update This Collection (Code: 409)

Apologies the problem seems to have corrected itself.
