Menu items not accessible

I can enable all but System MaxiMenu CK (see attachment) With System MaxiMenu CK enabled I get the error message.

you must disable "Maximenu CK Params" and enable "System - Maximenu CK"
is that ok ?

I don't have Maximenu CK param but do have System - Maximenu CK Params.
So, you mean:
enable: System - Maximenu CK
and
disable: System - Maximenu CK params ?
that doesn't work and gives the same error again.

yes this is what I mean. According to the explanations here:
forum.joomlack.fr/index.php/4-maximenu-c...maximenu-ck-v8-to-v9
you must enable the "System - Maximenu CK"plugin and disable the "System - Maximenu CK params " plugin
then disable the other plugins type "maximenu" as before (adsmanager, articles ...Etc)
check if it works : if ok, then enable them again one by one

let me know about the result (you must not use the Params plugin anymore, this is to be used with the old V8)

I'm sorry to say, but......
I removed the System - Maximenu CK Params (belongs to version and if I disable ALL maximenu plugins, it works and I can edit the various menu items. However, ones I activate the System - Maximenu CK, I cann't edit them anymore. Is it possible that something went wrong with the System - Maximenu CK plugin?

Mmoreover, I noticed that the Accordeon Menu CK Params is still availablein the menu items, although it was removed long ago from the website. See attachments
