Screen Names with Apostrophes not working - HELP!

[JustJamie]

We had to move hosting and in doing so, a few things got messed up. For instance, anyone with an apostrophe in their name no longer exists. A member tries to buy them a gift or change their title and it says user does not exist.

Please help. This is all new to me. I am still learning.
