UBB.threads PHP Forum Software Community Forums UBB.threads 7 Bug Reports Non Bugs [NotABug] Month of December bug?

Hi

I noticed when looking at an Edit Profile, then checked several and all is the same
When I look at birthday months December look weird.
I then checked the register page and it looks like this
it reads "DecemberPowered" see images below, Is this a general glitch or just mine??? Where can this be changed?
