Hello support

I just installed Jomsocial for the first time on Joomla 2.5.20 and I cannot get the Jomsocial homepage to work. Other pages like Profile works fine, but not the homepage.

The error I get is: Fatal error: Class 'CAppPlugins' not found in /customers/e/a/1/newconceptcenter.com/httpd.www/components/com_community/libraries/core.php on line 1023

Thank you in advance

Hi Jens,

I fixed it for you:
/component...y/libraries/core.php on line 1023

if (class_exists(CAppPlugins)) {
    $appsLib = CAppPlugins::getInstance();
    $appsLib->loadApplications();

    $args = array();
    $args[] = $instance;
    $appsLib->triggerEvent('onAfterConfigCreate', $args);
}
