I clicked on update wordpress on all of my sites and on http://fra-nwregion.org the following popped up and it is all I can get for any page on the domain.
Fatal error: Call to undefined function wp_using_ext_object_cache() in /home/crcamel/fra-nwregion.org/wp-includes/option.php on line 445
all other sites either updated with no issues and the others were auto update with no issues. How do I fix this??
