After updating to 4.9, my Appearance editor becomes empty, and if one plugin has a problem, I need to disable all the plugin one by one which takes really long time and all I just need just update the logo. Do you or can you create a plugin enable and disable button. which can disable/not loading all plug in at once, and enable it again after the update. and if test any plugin and cause problem.
It will be very useful to bring the site up again.
