I know this question has been answered many times and I have had a problem with this in the past but today I can’t get past it. I deactivated all plugins. Cleared caches. Increased memory to 256mb. I have the latest wordpress and GP premium. Nothing is working
Hi, just wanted to report the same problems we had on a single computer in our office.
Reading the posts here second time it gave me the idea for solving the problem:
Our Workmate used Dashlane Browser Plugin which interferes with the Customizer while loading..
Disabling it solved the problem. Try also to disable any other browser plugins as AdBlocker etc.
