headerphp

I've been trying to run a cloaker on my page (Binomo cloaker) and I simply can't access the page, this error keeps appearing and I don't know what to do to solve it. Does anyone know how to help me? Is there anything I can do to resolve this and be able to run my page?

I hav a dead niche site (SEO + ogads), however its still makes a little change. I went to check the the traffic on GA and there was nothing. I then went on to check my header.php to update the GA tracker after I hit save, the whole header.php erased itself. This site was making at one point...
