Facebook chat in OS X Messages shows numbers instead of names
Though I have used Facebook chat in iChat and now OS X's Messages programs for many years now with few issues (some disconnecting issues here and there but that's about it) The past few days I have encountered a problem that I can't figure out how to fix.
Whenever I first launch Messages and it logs me into FB chat, the names of my friends show up correctly for a handful of seconds. Then, suddenly all of the names and pictures disappear and instead turn into numbers (those aren't the actual numbers, just examples of what it looks like.) So my buddy/friends list becomes populated with all of these numbers and I can't tell who is who.
If I quit Messages and relaunch it, again I will see the proper names of my friends for a handful of seconds after logging in, but it always turns right back into a bunch of numbers.
I'm thinking this MUST be a server problem since not a single thing has changed on my computer.
Anyone else experiencing the same thing? Can anyone help?
Thank you.
