Multiple specification changes/page builder updates

【Contents of modification】
■Changed Facebook OGP setting from old specification (fb:admins) to new specification (fb:app_id).
※Please refer to the following article about how to get “fb:app_id” (application ID).

■Change the specification of the map display of the fixed page template 2 (ACCESS).
※We have changed the specification to display the map by using the “Google Map iframe code” or the Google Map settings in the theme options.
 With this change, the map displayed by the old “TCD Google Maps” plugin will no longer be displayed, so please refer to the download site to reconfigure.
