Script execution error

Hi,

I’m using Ocean WP 1.4.2
When I use the customization tool, I have a script execution error message every time.
The error is in :
https://mydomain.com/wp-admin/load-scripts.php?c=0&load%5B%5D=jquery-core,jquery-migrate,underscore,wp-a11y,wp-util,jquery-ui-core,jquery-ui-widget,jquery-ui-mouse,jquery-ui-sortable,jquery-&load%5B%5D=ui-draggable,jquery-ui-droppable,backbone,wp-backbone,wp-ajax-response,jquery-color,wp-lists,postbox,nav-menu,shortcode,utils,me&load%5B%5D=dia-models,plupload,wp-plupload,mediaelement,wp-mediaelement,media-views,media-editor,media-audiovideo&ver=4.8.2:2

Could you help me because when I click continue in the error message dialog, the interface loading is very long?

Thanks.
