The check that we use is in the /administrator/components/com_jfbconnect/views/social/tmpl/default.php file. At line 14, we make the following call:
$k2IsInstalled = JFBConnectUtilities::isJoomlaComponentEnabled('com_k2');Simply change that to:
Then, the error should go away.
With that said, the check we do for k2 is in the database. We're making the following query:
SELECT extension_id FROM #__extensions WHERE 'type' = 'component' AND 'element' = 'com_k2'
Try to run that query to see if something comes back for you. If so, let us know the details of that row, because something seems to be indicating K2 is installed in your database.
I hope that helps,
Alex
