Hello Tuanphan,
thank you for your time!
Yes sorry i made a mistake in the URL it is www.avrilkids.com
but i have manage to solve the problem in an other way,
i have delete the category menu, and uses the categories as links in the main menu, it's better for me like that,
the only problem now is that the menu is separated in the mobile version, we have to click on an arrow to see the categories. Do you know how i can solve that? I would like the whole menu to appear together.
Thanks for your precious help!!!
