We have updated our Joomla site. I completed updated on all other components & template and Joomla (3.7.3) before finally updating JomSocial. All was working until the JomSocial update from 4.2.5 to 4.3.5 (though update itself completed "successfully").
Are you able to assist ASAP, as the JomSocial pages will not load in frontend.
