Hello,

Error when saving the param : level1itemnormalstyles.
Error when saving the param : level1itemhoverstyles.
Error when saving the param : level1itemactivestyles.
....
....
Error when saving the param : layout.
.....
and so on.

I follow the tutorial and the documentation that come with that.
Does someone have an idea of what is happaning?

Thanks for your support.
