hacked site

[Topic modified – hacked code is not useful/relevant]

I’m also seeing the above link on my website at the top of the page even though Sucuri SiteCheck shows nothing wrong

I have gone through all the php files and cannot find the elements that Google Chrome is showing

I think I have allowed this in by installing a Plugin recently.

It is very sneaky as the URL is the same colour as the page itself.
