Thanks for letting us know, I know a few other users have experienced a similar issue. I’m working with our other admins to get it diagnosed and will update you guys when I have some more info.
In the meantime if you could screenshot any and all error messages you’re receiving and document steps to reproduce them that will be helpful.
What is the file size of the photo you’re trying to upload?
Iirc, Lemm.ee has a 500kb photo upload limit because we are not built as an image hosting platform it is highly recommended you use an external image hosting service. The restriction has not been changed to my knowledge.
