Like most political and religious things, it's complicated and the answer is often so wrapped up in 'technical' terms as to be almost unintelligible to the uninitiated. Hence it's much easier to say ....

..than to explain what it actually does mean
Though generally, IIRC, it means that the Pope is only infallible when basing his comments on the contents of the bible and when discussing religious matters. However, that is a gross simplification....and a more detailed investigation would show it to be wrong. Also, I believe that bishops/cardinals can also be infallible under specific circumstances.
BTW, it should be noted that I am not religious and so attempting to start an argument with me over such matters is a waste of time as I do not support the idea of Papal Infallibility. Also, please let us not run the risk of insulting those forum users who are religious by making tactless remarks about their beliefs.... As we have seen in the past, religious debate can often lead to fallings out. This is not to say that we shouldn't discus religion or question its principles etc, but that we should take care about how we communicate our views. I thank you.
