Hello
I encounter a strange behaviour related to the WYSIWYG editor (Tiny MCE).
On a WordPress post writing, it is the new version, it also is on the Newsletter plugin subscriptions settings (subscriptions page, confirmation messages, …), see screenshot :

But when writing a new newsletter, it is the old one :

What I did so far :
– Check for update, “force upgrade”, and “force upgrade from an old version” (my current Newsletter version is 4.2.2)
– Disable every extension, enable only Newsletter
If anyone could point me in the right direction, I’d be very grateful
Thanks !
