Help! How to remove this mystery letter in the header

Please see Somehow a developer who was helping me inadvertently added that “I” you see to the left of my logo (essentially, the very first thing on the site). Does anyone know how to remove it, please?

I’m The Issue theme by Fuel Themes and contacted them but haven’t heard back yet.

hello @csjary!
it’s better to remove it from file (but without access to ftp it’s difficult to say which one).
so you can add this js code:

$("body").contents().filter(function () {
 return this.nodeType === 3; }).remove(); 

hope it help you! (I am test if using console and it’s work)
