Reset Themes to supplied values ?

I had a menu which worked very well with Maximenu CK.

I tried the cssmegamenu theme, and tried changing some colours, but not very well.

Then installed the params plug-in.
But now the menus default & cssmegamenu theme don't show the colours the way I'm setting within the module set up, or menu item.

Is there some way I can set the Maximenu Module & Plug-in back to the supplied values, so that I can start from the beginning again?

url: www.ayrshirebridge.co.uk (theme default just now).

Thanks if you can help

A further question:

Why is it that when I enable the Params plug-in, the Horizontal menu appears different with Default theme?

Hi
please check that you have the last version of the plugin and the module
if the plugin is disabled you should not have the custom styles applied. Then you just have to select in the module style customization the options you want to enable.
To reset the settings, just create a new maximenu module and publish it instead the old one
