Event: "name is missing"

I had the same problem. What’s happening is that the plugin is outputting summary instead of name for the event. You can fix it by going into the plugins editor and editing the functions.php file for the plugin. Look for the line that looks like this:

$event .=' <div class="snippet-data-img">?<span itemprop="summary">'.$event_title.'</span></div><div class="snippet-clear"></div>';

Change the word summary to name so it looks like this:

$event .=' <div class="snippet-data-img">?<span itemprop="name">'.$event_title.'</span></div><div class="snippet-clear"></div>';

HAH! Works! Great and thank you very much for this!

google is showing error with this config within webmaster tools.

So have reverted back the plugins default code. i would also go over this

google discussion

Google & schema.org updated few properties that caused this. Latest 1.3.0 version has already solved this issue.
