I have recently installed the WordPress SEO plugin by Yoast and everything seems fine, in fact it is an amazing plugin... The only problem is that when i perform a search i get this error message
Fatal error: Call to undefined function is_post_type_archive() in /home4/bloghote/public_html/blog/wp-content/plugins/wordpress-seo/frontend/class-opengraph.php on line 124
Line 124 is where my login box is, but the error message says something about the opengraph.php. I have tried doing a search logged in and logged out but it still appears... any ideas?
