I need to give color to each particular event.
For this it occurs to me give a different style to each table, calling the "class =" a category for the event, so I did this:
eme_calendar.php (Line 396)
$calendar=str_replace("<td class='eventless'>".$cell['day']."</td>","<td class='".$event['event_category_ids']." eventful'>".$cell['cell']."</td>",$calendar);
<td class="3 eventful">...</td>
But when I have more than one event, I only get the id of the first event.
