For a couple of days I cannot sign out of my one account to get into another account on separate emails. I have reported this now numerous times. The "item description" for all listings - mine and others have disappeared then comes back ( sometimes). I still have an erroneous item in my purchase history that states "it needs to be paid" and has been there for a month and I keep telling ebay about this. I cannot do business like this and am dead in the water - they said they will "escalate" the ticket while it feels like they are ignoring it.
What happens when you clear cookies and browser history? Because it sounds to me like you have corrupted cookies. If you are getting to your eBay using bookmarks you may need to delete that and start over as well. Hope that helps.
Try using a different browser for different eBay accounts, then you never need to sign out. Or use a private or incognito browser window so you can stay signed in in your primary browser window.
I "escalated" it up to a supervisor - it apparently was a site wide issue - Yes, cleared caches, cookies, restarted, changed browser, stood on one foot and hopped in a circle. They had it fixed in about 48 hrs
