@collectiveaccess Reprocessed. There are some messages when reprocessing. I don't know if related to the problem:"gm.exe convert: No IPTC profile available C:\Users\xxx\AppData|Local|Temp\xxx.tem.iptc". After reprocess, tried Mirador shows no preview, just black screen with word "Add item", and Universal Viewer shows "Unable to load TileSource". How to let CA to generate TileSource? Thanks.
