Thx Jan..
I installed the plugin, but I could really need some help. The http is changed to https - I don't know why http was in the source code. it is not anymore.
I am working on seo. and i get a lot of issues in my seo tool: Open Graph tags incomplete.
EG:
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<meta name="keywords" content="Spiegellijm" />
<meta name="title" content="Spiegellijm bestellen" />
<meta property="og:site_name" content="JAJA Lijstenmakerij" />
<meta property="og:title" content="Spiegellijm bestellen" />
<meta property="og:description" content="Spiegellijm voor het bevestigen van spiegels aan de muur." />
<meta property="og:url" content="
https://www.jaja-lijstenmakerij.nl/more ... piegellijm" />
<meta property="og:type" content="website" />
<meta name="description" content="Spiegellijm voor het bevestigen van spiegels aan de muur." />
<meta name="generator" content="Joomla! - Open Source Content Management" />
<title>Spiegellijm bestellen</title>
I have no idea what is missing or what needs to be changed..
