Hi Paul Murray,

Regarding your issue, look like there is a bug in Wanderers theme overriding for EasySocial stream action buttons. Below is the error I get when I enable error reporting.

Fatal error: Call to a member function getHtml() on a non-object in JOOMLA/templates/wanderers/html/com_easysocial/stream/actions.php on line 116

Anyway, I've added a fix on your site and now the group page should display correctly.

For anyone that having the same issue, please download the attached actions.php and copy this file to folder 'JOOMLA/templates/wanderers/html/com_easysocial/stream/' and replace the existing actions.php.

The same fix will be added into next release of EasySocial as well

Hope this help and have a nice day!
