Wich error? There’s some expected failures on page now because of deactivation of contact-form and the gallery used on my portfolio. But it is under control. I think it not affects the behavior of the main menu, but I can reactivate it if you want.
I also did these two changes on theme structure:
1. I updated Font-Awesome to use new icons;
2. For larger interval of Carousel, I’ve changed these lines on owl.carousel.js:
base.options.autoPlay = 15000;
