Each post on my site has two meta name="description" tags. The correct one is inserted by the Ultimate SEO plugin. The second one is being inserted by wp_head.
On some pages the second tag says content=" " and on other pages it says content="null "
If it helps, the three lines above the bogus tag are:
<meta property="og:type" content="article" />
<meta property="og:title" content="Quilting Books For Beginners" />
<meta name="title" content="Quilting Books For Beginners" />
and the line following it is:
<meta name="medium" content="blog" />
Can anyone suggest where these bogus tags are coming from and how I can make them stop?
