Facebook problems

I know this is probably the wrong board to be in but... I use safari on windows, and whenever I recieve a message on a facebook chat thing an error window pops up saying "Safari can't find the internet plug-in. Some contents on the page 'Facebook | Home' can't be shown because its MIME type is unspecified."

Possible solutions?

Looks like other people are having the same issue:

chat not working | Facebook

Looks like you may have to reset Safari or at the very least empty your cache. It looks like it was a change on the Facebook side, not a browser issue.

To empty your Safari cache go to Safari-Empty Cache (or find this on Windows I have never seen Safari on this platform)

To reset Safari go to Safari-Reset Safari

I would also logout of Facebook completely and re-login. Note if you don't do any of the above steps, it might be helpful to at least delete your cookies.
