I recently upgraded from Joomla 3.10 to 5.3.4 without any issues. I followed the upgrade instructions as written by Joomla. All extensions and plugins are current. I am using Helix Ultimate. I had to uninstall and reinstall the template during one of the compatabilaty checks during the upgrade. The website loads from the admin backend when previewing, but shows the site is offline from the frontend when I am not logged in. If I switch the default template to Cassiopeia the site loads from the front end properly. Any assistance will be appreciated! Thank You. www.africankillerbeads.com
