'There was an error uploading your item to the Gallery'

crinrict​     I am having this issue also . It has been a month or so since I last uploaded a Lot to gallery. I have tried to upload a lot (part of a Halloween group worlds build) .  I first tried to upload My lot to gallery a week or so ago NO Lots will upload. No cc . I tried a 2nd build incase first one was too much.  -Server error... can't process this gallery request, try again later.    I even tried a plain lot, just raised terrain and put a simple rectangular box then tried to save to My own lot catalog . Nada!    I can not upload or save Any lots to My own catalog.   I was able to upload 1 Room on it's own , thats all.   The deadline runs out soon to get My upload submitted for the group H'ween Project.   this is so frustrating
