These errors are weird, as they are new... I should maybe try to restart the server some day, it is different from the usual issue we had before.
550 ? max height is 498
I don't see why it would show such message
Just happened to me too, and for some reason it won't upload any images 
it shows a message saying maximum height 550px (but images are under that height, and it has uploaded images from the same batch and format)
