Hi,
Yes, I have. But after disabling “Object Cache” (https://screenshooter.net/3241371/fsbeubk) Ultimate TinyMCE started to work again :).
My advanced settings of “Object Cache”: https://screenshooter.net/3241371/okfndgl
EDIT: Strange.. When I turned off “Network Performance & Security powered by CloudFlare”, Ultimate TinyMCE disappears again. I’m refreshing page with Ctrl + F5 after changes which I made in W3 Total Cache.
EDIT 2: Even stranger.. “Object Cache” is off and Ultimate TinyMCE dosn’t work. After deselecting Minify it’s working again.
Summary:
Object Cache: off + Minify: off = Ultimate TinyMCE works.
