A few days ago, I noticed when I open the customizer on any page, the preview comes up but all elements are non existent, and only shows the plus sign to add more. I’ve increased the wordpress memory limit and tried deactivating all non-essential plug-ins.
This issue was caused from Mailchimp Plugin. Please be sure to install and activate Mailchimp Plugin as required from Theme. If this will not fix the issue, please contact me back.
