7.0.1 has Beaver Builder conflict

Note: This is on a site being developed, and is not publicly accessible, however I can provide access upon request.

The error below is displayed when I enter Beaver Builder mode on any page. It only occurred after I updated to 7.0.1. The error goes away when I roll back to 7.0.0:

Beaver Builder has detected a plugin conflict that is preventing the page from saving.
( In technical terms there’s probably a PHP error in Ajax. )

If you contact Beaver Builder Support, we need to know what the error is in the JavaScript console in your browser.

MacOS Users:
Chrome: View > Developer > JavaScript Console
Firefox: Tools > Web Developer > Browser Console
Safari: Develop > Show JavaScript console

Windows Users:
Chrome: Settings > More Tools > Developer > Console
Firefox: Menu/Settings > Web Developer > Web Console
Edge: Settings and More > More Tools > Console

Copy the errors you find there and submit them with your Support ticket. It saves us having to ask you that as a second step.

If you want to troubleshoot further, you can check our Knowledge Base for plugins we know to be incompatible. Then deactivate your plugins one by one while you try to save the page in the Beaver Builder editor. When the page saves normally, you have identified the plugin causing the conflict. Contact Support if you need further help.
