Issue in footer of page: garbled mysql

https://www.spacemodel.com

I’ve got garbled code showing in the bottom of the main column on my site and I haven’t done anything with core files or templates/php that would have caused it. I think it’s an issue with the mysql database being changed without my knowledge but before I spend the time to go down that rabbit hole I thought I’d ask here for advice. It’s driving me crazy – host says password/user combination for db has nothing to do with the error and I don’t know what else it could be.
