Recieving error message on all pages (inc dashboard) “script called incorrectly”

I’ve been having issues with a certain page on my website so I contacted my host provider who added a debugging code to my config page. Which caused an issue on all of my pages on the website (and even stopped me from using the dashboard and posting pages).

– After removing that debugging code because it didn’t work. The notice message didn’t disappear and the page was still not loading!! So now there’s two issues!

I spoke to a fellow blogger who read the error and told me to disable my plug-in for blogger2wordpress which removed the notice message on the main page but it still flashed up before the page loads AND it’s still on my dashboard too.

So – Can anyone tell me what’s going on with this one page “https://purelyamy.co.uk/my-first-blog-post-six-years-giveaway/” and how to fix the website flashing the Notice message? Now I’m getting this on my dashboard..
