I’m using Jerboa v0.0.40 and I can upload images just fine in any community from any other servers, but it doesn’t work with communities hosted on sh.itjust.works. Error I get it “Value <html> of type java.lang.string cannot…” I can’t see the end of the message.
The last time this happened to me, and then I retried in a browser, I found the image was being rejected due to a size limit. Jerboa just doesn’t handle the error properly.
