Nope. I had tried to list a shirt yesterday and it didn't go through. I can't remember what the problem was and I was listing it for $1 anyway, so I couldn't really be bothered.
Hmmm never noticed this happening - is it occurring while you're in the middle of doing something or after visiting another site/taking a break and not using your computer? maybe it has a time out logout.
So far only after not using the site for a while, but usually only maybe 30 minutes or so. And I'm not closing the browser, navigating away or anything like that.
They look really low quality and blurry. I dont understand why since my source images are good quality (can't link them in the message since this forum only allows me to post one URL per post!?)
I've tried re-uploading them, and even changing the file names to no avail. I've not had this problem with any other listing.
