I'm using WordPress to power my website but Elegant Themes for the design theme.
The theme is called "Flexible" and the 'Home' page will not load. Instead a blank page appears with the message :
Fatal error: Call to undefined method WP_Query::is_main_query() in /homepages/26/d393316612/htdocs/app393316625/wp-content/themes/Flexible/functions.php on line 175
The other pages work fine, only when I click on 'Home' or try to load the website in the address bar (added-insight.co.uk) that it comes up with the failed message.
Any help greatly appreciated.
