Hi when I go to log into the dash board of my site http://www.hellforleather.com.au/wp-admin/ I receive the following error message
Fatal error: Call to undefined function wp_is_mobile() in /home/hellfour/hellforleather.com.au/wp-admin/includes/misc.php on line 586
Please advise how I can fix this Many Thanks Angelika Koop
Try re-uploading all files & folders – except the wp-content folder – from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones.
