Top Header Dash on every page top left. Cannot figure out how to fix this.

On my desktop version 7.0 brine the top of every page has a  backslash \  on every single page.  I have tried to go under style and edit the tope header but there is absolutely no dash in the design.  Has anyone had this happen before?

In Settings > Advanced > Code Injection > HEADER I think you'll find you have a syntax error in the code.

Remove the backslash.

Let us know how it goes.
