Replace Yootheme Menu with Maximenu CK

now it is in top-a but as before. it shows only the title. but in this template i need to put it up or down the menu module position

Do you have set the module to show a menu where you have some menu items ? strange that the menu is totally empty
You can try to create a new maximenu module into another position. What I see in your code is taht there is nothing from the maximenu module that is loaded.I wonder why you see the title ...

it should show the main menu. i have selected it.

Could i give you a pw and id to enter in my admin area?

i changed the template. i changed to Clever and the result is always the same.....nothing. i think i am unluky. and i cannot install it.

Please can you help me? or i must uninstall it

I would suggest testing with a default Joomla Template (Protostar), follow Cedric's instructions to setup the menu from scratch and see if that works, if it does then it is an issue with modifying theme config files. Paste the modifications you have made to your Theme's config file, it will help to see what may be causing the problem.

Cheers.

for sur the module is absolutely not loaded, so this is not a Maximenu issue
Now you can try to create a new module like suggested to test
the Clever template, I don't know it but this is not a joomla standard template. Try with protostar or beez according to the nice suggestion of nsheehan13
