Fatal Error after upgrade to 6.0.2

I just had the same issue. Artbees support told me to make sure you update your php settings to 7.0 on your server where the site is hosted. Then refresh. Solved the issue. Hope that helps you.


Thank you so much. Resolved.


Jupiter is compatible with PHP 5.6 or higher.

Please contact your service provider and ask them to upgrade the PHP version to at least 5.6



I’m using PHP 5.6.3 and have the fatal error issue. I’m reverting back to an older version of Jupiter for now.


I’m getting the same issue, but upgrading the PHP settings didn’t work.


Ok, just took a few min to update. Now it’s working
