ISSUE SUMMARY:
When upgrading from JS 4.0.10 to JS 4.1, the upgrade goes okay but the front end wont load.
On investigation, it seems that some of the new functions aren't being loaded.

The error message provided by Diagnostics is as follows:
Fatal error: Call to undefined method CSystemHelper::tfaEnabled() in /home/www/kiwiklub.com/components/com_community/templates/jomsocial/layouts/frontpage/guest.php on line 39

If I comment out the 2-factor authentication helper code, then I get a similar message regarding the user online function

Hi Marc,

the files at your site not same with jomscoial 4.1.1 version. seem the issue with server permissions.
make sure all directories having 755 permission and 644 for files.

and please re-install your jomsocial. no need to uninstall anything.
you can download jomsocial 4.1.1 from jomsocial.com > my account.
after that you can install it from joomla extensions manager

Regards
