Can’t Customize Jupiter X



I have tried all the usual and customary attempts to resolve the issue with no luck.
I am hopeful you can help me navigate to the ‘customize’ screen.
Error message “ There has been a critical error on your website. Please check your site admin email inbox for instructions.”

Here’s a screencast of the issue…


The problem existed in WP 5.2.4 and in 5.3

Thank you in advance,


Im having the same problem after updating to wordpress 5.3, need to customize footer. And customizer wont load, junt hangs on loading: wp-admin/customize.php . Console message is: Failed to load resource: the server responded with a status of 503 (). Next time I will just wait to do these updates after jupiterx has fixed its own
