I've experienced this problem since earlier this week but I thought it was a one-off thing. But it has been persistent and I think that it's a breach of privacy??

Initial Problem: When I view my lists, it'll sometimes show that I'm logged in as someone else and their lists are fully editable by me (I swear I didn't change anything in their lists). I'll quickly refresh to get back my list.

Current Problem: My 'Completed List" is permanently showing as someone's else list and I'm always logged in as that same stranger whenever I view the list. Problem wouldn't go away no matter what I do - Refresh, Re-logging in, etc.

Hope this can be solved asap 'cos people may edit others' lists unintentionally and mess them up.

A similar case has happened before...

You should also add a screen shot.

Couldn't get a screenie for the past few days 'cos it was working fine again till today.

Note: I'm seeing yet another person's account today. Plus it only happens to my 'complete list'.

Proof

im having a problem with my list too.i tried adding a series on my wish list to my reading list but it would not let me. this was a couple of weeks ago. i figured it must be a problem with my computer but it didnt go away and now i cant add anything to any of my lists.. i can delete things from them but i cant add anything to any of them

Have you tried a different browser? Try to delete your cache. Make sure JavaScript is enabled

i tried all of those things. i use Firefox as my browser and it worked perfectly up until a few weeks ago. It did work when i used Internet Explorer but its just so slow it takes five minuets just to open it up. and Yes Java is and was enabled. and i deleted the Cache but it didn't help is there any thing else you can think of

Have you tried to reinstall Firefox? And it's JavaScript, not Java. They're different
