Hello,
When I click on the menu icon the menu does not expand.
My website is www.classin.ro
Can you take a look?

Hi,

I can see you have updated cornerstone to latest version but forgot to update your theme.

Please update your theme to the latest version X 6.0.4 to avoid incompatibility issues like this.

Thanks
