This is the error that was sent to me to fix.
Priorities to be addressed:
Checkpoint 2.3 | Subhead - Titles of pages should not be used in the subheading.
I read the documentation, but I still don't have a clue where to look to fix this.
<h1>Site Title</h1> <h2>Subheading -- tagline for your department</h2>
The subheading is meant to be a promotional or descriptive piece of text for the entire site. The title for an individual page within your site should go at the top of the region titled "maincontentarea."
