Sitemap not working – Uncaught Error:

You can see by following the link, I’m having an issue generating site maps.

I’ve tried removing the plugin and the tables from the DB and reinstalling but I still get the same error.

Fatal error: Uncaught Error: Call to undefined function wpseo_xml_sitemaps_base_url() in /home/nick9417/public_html/westyorkshirewindscreens.co.uk/wp-content/plugins/wpseo-local/classes/class-core.php:284 Stack trace: #0 /home/nick9417/public_html/westyorkshirewindscreens.co.uk/wp-includes/class-wp-hook.php(286): WPSEO_Local_Core->add_to_index('<sitemap>\n') #1 /home/nick9417/public_html/westyorkshirewindscreens.co.uk/wp-includes/plugin.php(203): WP_Hook->apply_filters('', Array) #2 /home/nick9417/public_html/westyorkshirewindscreens.co.uk/wp-content/plugins/wordpress-seo/inc/sitemaps/class-sitemaps-renderer.php(67): apply_filters('wpseo_sitemap_i...', '') #3 /home/nick9417/public_html/westyorkshirewindscreens.co.uk/wp-content/plugins/wordpress-seo/inc/sitemaps/class-sitemaps.php(370): WPSEO_Sitemaps_Renderer->get_index(Array) #4 /home/nick9417/public_html/westyorkshirewindscreens.co.uk/wp-content/plugins/wordpress-seo/inc/sitemaps/class-sitemaps.php(314): WPSEO_Sitemaps->build_root_map() #5 /home/nick9417/public_html/wes in /home/nick9417/public_html/westyorkshirewindscreens.co.uk/wp-content/plugins/wpseo-local/classes/class-core.php on line 284
