I have a similar question, I had to deactivate WordPress SEO because it caused a Fatal Error on my homepage
Fatal error: __clone method called on non-object in ../wp-content/plugins/wp-views/embedded/inc/wpv.class.php on line 788
it seems there is a conflict between the two plugins.
But do I lose all the features of SEO if I deactivate it over the weekend to sort this out?
