Deactivate (NOT uninstall) one by one and see if the error is gone. That may tell us if PublishPress Blocks is conflicting with a particular plugin. * Thread Starter [legraindeweb](https://wordpress.org/support/users/legraindeweb/) * (@legraindeweb) * [4 years, 4 months ago](https://wordpress.org/support/topic/javascript-error-on-admin-page-for-page-modification/#post-15245011) * Seems to go away once i deactivate Genesis Custom Blocks I have custom blocks based on it so i can’t do without it unfortunatly.
