I'm using a static page for my 'Front page', and a page called 'blog' for my 'Posts Page'. Everything works fine, except that /blog returns an index when it used to return all my posts. When I try to edit the page called 'blog', I get the following error:
Fatal error: Call to undefined function: _weak_escape() in /home4/laylocko/public_html/wp-includes/wp-db.php on line 487
Any help would be greatly appreciated.
