There are words on my header

Hi there,

Do you have any Hook Elements in "Appearance > Elements"?

If so, does that text exist in any of them?

I do not have any elements. In fact I changed my theme and I still have those words.

Then it's likely from a plugin.

Try #1 here:

Let us know :)

It was a plugin. It is now resolved. Thank you.

No problem :)
