I made sure that in add ons < modules, RTE is installed.
Clicking on ‘Rich Text Editor’ I also made sure that RTE is enabled.
In ‘My Account’ section ‘Rich Text Editor Preferences’ it is enabled too.
In Channel XXX > Edit preferences, the option ‘Display Rich Formatting Buttons’ is set to ‘yes’.
But when I publish an article in this XXX channel, there is not RTE buttons that display.
Have I missed anything?
