Your database appears to need patching to a higher level.

Upgraded from 1.5.1 to 1.5.3. My latest PHP version supported by Cpanel is only 5.5. I know the requirements says 5.6, but will it still be OK with 5.5? If so how can I remove the error from the top of my web site index page.
Everything seems to be working.

You need to also upgrade your database to 1.5.3.

Thanks,
