I set up an event more to try it out than anything, so I don't need this fixed am just reporting it for your information, two users on my site who were not taking part in the event "Liked" something in it and ES sent out two email messages the subject was
"APP_USER_EVENTS_GUESTS_EMAILS_CREATE_LIKE_ITEM_SUBJECT"
and the message in both emails was
Warning: include(/home/cityb.../public_html/media/com_easysocial/apps/user/events/themes/default/emails/html/guests.create.like.item.php) [function.include]: failed to open stream: No such file or directory in /home/cityb.../public_html/administrator/components/com_easysocial/includes/template/template.php on line 290
Warning: include() [function.include]: Failed opening '/home/cityb.../public_html/media/com_easysocial/apps/user/events/themes/default/emails/html/guests.create.like.item.php' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/cityb.../public_html/administrator/components/com_easysocial/includes/template/template.php on line 290
Its not causing a problem on the site, and both "likes" have been recording, so it just seems to be a problem with the notifications.
