Help with Core Mods


I’m getting this error on my site all of a sudden and have no idea how to fix it.

Warning: Use of undefined constant core_mods – assumed ‘core_mods’ (this will throw an Error in a future version of PHP) in /nfs/c10/h07/mnt/144394/domains/nationsfg.com/html/wp/wp-content/themes/nationsfg/functions.php on line 50
