Mobile menu on left module position

Hi,
i installed mobilemenuck-light_1.5.11.
I'm trying to configure it but I can't. I have menu module on left position.
I enable "Enable Mobile Menu CK" in Mobile Menu CK tab.
but notting happens

Can you help me, please?

Hi
please go in the module options >> advanced >> css suffix >> add " nav"
this shall work else your template is in cause because of an override
let me know
CEd

I already tried that, unfortunately it didn't help.
I use this template (Joomla 3.x):

please try with the template Protostar , pubish the menu module in a position of the template and see if it works
if yes, then the problem comes from the overrides, and you shall be able to remove the override of the mod_menu from your template

I can't just change the template on the production site. So I made a backup and put it elsewhere.
Then I switched the template. So it works on Protostar.

Please, so where is the problem? I did not use any "override".
I can give you access to that backup website. I just need to know your country so I can unblock access to the admin..

this is something from your template
try to edit in the menu module >> advanced >> layout >> select another layout if got it
else you can try to use the free version of Maximenu CK
www.joomlack.fr/en/joomla-extensions/maximenu-ck
which is fully compatible with the mobile menu and where your template will not interfer
