I started a fresh install. The EVO version has been obtained from the link on the new website (it says 3.1.10 but shows 3.1.11CE after installation).
I guess I got the new version then.
Installation went smoothly (PHP is 7.4)
but
Why is version 4.3.7 offered as editor?
The last EVO versions had the TinyMCE version 4.9.11.
No setting can be changed in the configuration!
The theme is set to "advanced" and cannot be changed.
The language does not match the setting (DE for me)
The fields in the configuration for Custom each contain a corresponding entry [+tinymce4_custom_plugins+].
The HTML schema is set to HTML5 and cannot be changed either.
In the resource field of the editor on the content page, the font entered there is very very small.
The displayed editor buttons (Advanced?) can be used.
In this state, the editor is actually not usable.
Adjustments to the custom parameters (configuration tab) do not display the editor on the content page.
A lot of what could previously be configured and used without problems is no longer available.
So I would be very grateful for hints and help to have a usable editor available again.
