 * With the recent update to the plugin and the introduction of the archetype functionality,
   it works fine in regular WordPress, but is triggering the following error message
   in a WordPress Multisite Network setup:
 * **Warning**: Undefined array key “cpt” in **/home/bethshalom/public_html/wp-content/
   plugins/events-manager/classes/em-archetypes.php** on line **706**
 * Can you please fix and release an update ASAP? This is broken on several websites
   of mine, and the error message is public-facing.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcpt-archetype-update-triggering-error-message-in-wordpress-multisite%2F%3Foutput_format%3Dmd&locale=en_US)
