Hi,
The SSL cert is incorrectly configured for apache breaking curl.
curl https://theme.co/
curl: (60) Peer's Certificate issuer is not recognized.
This broke the wordpress admin page when it was checking for updates to plugins.
Fatal error: Cannot use object of type WP_Error as array in ../wp-content/themes/x/framework/functions/global/admin/addons/class-update-api.php on line 86
You can see the issue here https://www.sslshopper.com/ssl-checker.html#hostname=theme.co and it links to the instructions to fix your server http://www.digicert.com/ssl-certificate-installation.htm
