I have recently started using the site seobility.com to check my sites and finding it very useful. But it has found a fault on one of my two sites built with Rapidweaver 8. It has found different charset encoding on all pages of one of my sites. the site is (https://www.christleton.org.uk) It reads
HTTP-Header Content-Type : text/html; charset=ISO-8859-1
Meta http-equiv Content-Type : text/html; charset=utf-8
Meta Charset Attribut : utf-8
I have set English as the Site Language on the General Setting page. I can see utf-8 in the code for each page but searching for ISO-8859-1 I find nothing.
Any guidance would be appreciated.
