Maximenu Pro CK style problem

Hi!
In the module, under Style, there is a possibility to change the style. I click on Select and an empty window shows up with no files. When I click on New I get an error and have to go back to Control Panel. So I can't change the styles on my menus. Otherwise it's a great extension!
Using Joomla 4.0.5, PHP 8, and the latest Maximenu Pro CK

thank you for the access
I have edited the style, changed the background color and saved, it works as you can see on your website

anyway, I have seen the error when you create a new style using the NEW button, so I will try to reproduce the issue by my side and I will let you know

Thank you for the help and the rapid respons!
Have a nice weekend!

Hi CEd!
Can you tell me where the demo file, for the style option, is situated? I wish to use maximenu on one of my other sites but I can't find the file.
Is it the files under modules/mod_maximenuck/themes/custom/css ? And can I copy them to the same directory on the other server or do I have to hack my database?
I've been using five different css-files since you helped me. I copied your file demo and renamed the files. I can't find them under the Joomla directory when I search for them.
By the way THANKS for your help and for Page Builder Pro (The best blog function I ever seen)!

for maximenu, sorry but I don't understand what you mean. To style the menu you can do it in the interface : module options >> style >> edit
you don't have to play with the css files unless you want to create a custom theme with your own skills
