I am trying to pass a WCAG 2.0 (Level AA) in a website and I can't understand what should I change. It gives me 2 errors. The first error is :
"Modify the header levels so only an h3 or any header less than h3 follows h2."
This is in the footer of the webpage which has 4 columns. All columns are h2 but it always shows me an error in the last one.
The second is a little complicated.
The error is :
"Modify the id attribute value so it is unique."
I have changed the id from page-id-44420 to page-id-12345 and it still gives me the same error. The website is in wordpress and the link is https://www.ferkonal.gr/
The website that I check WCAG is https://achecker.achecks.ca/
