Yoast Premium Conflict

I have worked with the developers at Yoast regarding their Yoast Premium plugin conflict and they are still not able to resolve the issue.

I am having two issues:

1. I am not able to upload featured image in blog posts
2. When Yoast Premium is not active it is now causing my sliders and sections of the site not to load.

This is the info they provided to me

Hi Bianca,

Thanks for granting us access to your staging site.

We accessed the admin panel, disabled all non-Yoast plugins and the problem still occurred. When editing a post or page, multiple JavaScript errors appear in the browser’s console (see screenshot below). On the other hand, we observed that your website is running several Must-Use plugins that can’t be deactivated (link here). As we haven’t been able to reproduce this issue in our testing environment, we suspect that one of the Must-Use plugins may be conflicting with the Enfold theme and Yoast SEO Premium and causing the errors.

We managed to fix the errors by implementing the suggestion provided in this support forum thread https://wordpress.org/support/topic/failed-to-load-jquery-at-load-scripts-php/ . This is adding define(‘CONCATENATE_SCRIPTS’, false); to the wp-config.php file. At this point, we’d recommend you contact your hosting provider and bring this issue to their attention. They should be able to look further into this issue and confirm whether the implemented solution is compatible with your WordPress setup as well as figure out whether any of the Must-Use plugins required by them may be causing the errors.

Please, let us know if you have any other questions.
