Bug?

This has started popping up this morning above the header:
Just thought I'd let you know John, or anyone else who knows coding might be able to quickly diagnose what the go is, be it a forum issue or just my computer. I can still peruse the forums fine, I just happened to notice this popping up in each page I open on Boosted.
Cheers
