Version number unchanged after installing 3.1.0

I just finished an install of 3.1.0 going from version 3.0.4, yet my version number still displays 3.0.4. I have done multiple upgrades of nagios with no issue since version 2, although this time something is not getting changed. It appears as though the html is not getting over-written with the new code. Can anyone give me some advice?

Thanks,

EDIT: it actually appears that only the “Home” page information has not changed. It is still showing 3.0.4 in large red numbers however on the tactical overview it shows:
