Hello,
Is there any solution to this issue? Customizer works fine in version 2.2.9, updated to 2.3.1 and all customizer options are gone. Reloaded backup of 2.2.9 and everything returns to normal. I have tried deactivating all plugins to flesh out if that was the cause, alas there was no change. Please let me know if there has been any solution found for 2.3.1.
