"Problem with saving your changes" message from Etsy when I try to list an item

[platecrafts4u]

Why am I getting this message when I attempt to list an item.  There is a long error code and it's really a pain trying to go through all the steps.  I'm not doing anything different than usual and have never had problems before.  Would be NICE to be able to speak with a live person from Etsy...not happy!!

Try another browser? Restart your computer, clear cache and cookies. A lot of error on here seems to be browser related. And it may flash error one day and not the next. Double check your listing and look for any red "you missed this" banners. If all else fails copy an existing listing and edit that.
