So in sold you have changed the drop down menu to 60 days as sometimes it might change by itself to 24 hours.

Other than that I can suggest the obvious, clear cookies, temp internet files and restart computer.

Then use chrome or firefox as browser if not already.

Also check in deleted under all selling, if there, undelete.

Going by anna's post, looks like an ebay glitch. 

Been having same problem come and go for last 2 days. Nothing I try has fixed it permanently. I am able to access my recently sold items by changing period in the sold section from 60 days to 7 days

I'm also having trouble with my sold listings. I need to let my customers know I have posted their items and like you it says I havn't sold anything. I would say Ebay is having another issue!!! I hope they fix it soon!!!

I am having the same problem. last 7 days won't work either. Last 24 hours does thank goodness as I have just sold two items and had to send a combined invoice

Hope it is fixed soon !!
