How can I repair the damage from a bad image banner code?

[TbB444]

I added a code in my image banner code and I ruined my entire store. Can’t go back because I saved the damaged code. How can I fix this issue?
There is a bunch of red errors on my page. Can some help please. URL : sheslays.co

@TbB444 , This will require store access to remove the code.
