I am a Jeffrey Friedl's “Export to Flickr” Plugin user since many years.
Yesterday morning Lightroom Classic passed to V13
I used LR/Mogrify 2 and LR/Export to Flickr for many years now.
With previous version of Lightroom Classic I used Mogifiy without problem with Export to flickr
This is an example uploaded Oct 7th 2023 https://flic.kr/p/2p7NDVm
This morning, after updating to LR V13 and Register Export to flickr the export of new pictures gave only the picture without its frame producef by Mogrify
This is an example of the frame free picture uploaded this morning : https://flic.kr/p/2p8vNW9
I also tested exporting with LR/Mogrify 2 alone in a picture file, it worked just normally
LR/Export to Flickr alone also worked normally but not the mix of two!
