Problems sending, replying or receiving messages?
What looks different about the format? Inbox or message composition screen?
Desktop or mobile?
What does the error say?
Try a private or incognito browser window, and temporarily disable any add-ons or extensions -- or try a totally new, unfamiliar browser. If the messages load fine there, likely something about your other setups -- cookies, cache, settings, add-ons -- is causing a problem for you.
Or try using the eBay app. Or try signing in to ebay.ca and reading/sending message from there.
Some users have been encountering problems when replying or adding images to messages.
Try going to a user profile or feedback page and composing a new message, and do not include any images. Does that work any better?
