Submenus do not open (the "+" sign does not work)

Hello,
Congratulations for youw excellent module!
I have a problem: Accordeon functionallity does not work. the submenus do not display when i hit (or hover) the + sign..
I'm using the latest Joomla ( 3.6.5) and the latest Accordion CK module (I downloaded yesterday).
I know I have some jQuery issues, because the console says:
Uncaught TypeError: jQuery.noConflict(...)(...) is not a function.

Because I know nothing about jQuery , your help would much appreciated.

Thanks

Thanks for your quick response.
Here is the link:

you are right, this error is the cause. But this does not come from the Accordeon module

Try to disable the system and content plugins for
- Ark editor
- JCE Mediabox
also
- module superfish menu

and see if the error is gone

else your theme could be in cause

You should ask on the joomla.forum.org to look for a better help on this

Thank you so muck CEd !!
It was the Ark Editor.
I disabled the editor and made default the JCE Editor again.
The accordeon works like a charm now!
You'll have a very positive review at JED website!

cool, thank you for the infos
I have already noticed that Ark editor can cause some issues ...
