 * I upgraded Events Maker to version 1.6.3, without knowing that there would be
   a compatibility issue with the formatting. The company that built the site said
   it should not be upgraded. So I disabled the plugin and re-uploaded the previous
   version from a back-up. When I go to activate the plugin I get this error:
 * Fatal error: Call to undefined function Events_Maker() in /home7/_[host directory]_/
   public_html/wp-content/plugins/events-maker/includes/class-taxonomies.php on 
   line 19

 * Events_Maker() is the final class of the plugin. It MUST be there.
 * Maybe something went wrong with the upgrade?. Just try to do that again.
 * btw: I’m shocked with your web design company statement. did you ask them why
   they mean?
