I recently moved my Library to a different drive, all my folders are relinked, but Quick Collections and Collections thumbnails and photos are greyed out... the number of photos next to the collection is showing up, but inside it's just grey thumbnails and photos... any ideas?
Please check the same images in Library mode, are they visible and can you edit them in develop mode? If not, then you need to relink those images. refer: How to find missing photos in Photoshop Lightroom
Also, restart Lightroom.
Thanks for the quick reply! I can't get any file numbers from them in Library mode. I did have a slightly older version of the catalog on my travel laptop, loaded the catalog on my computer and the photos showed up in the collections... weird? Anyway to export those collections into my newer catalog? Are the images in my newer catalog not showing up because the catalog is corrupt?
