Catch – Base : Mobile Menu when using Polylang

Hi, First of all, thank you for this nice responsive theme, very useful for a small company website. Here is the URL of the "on going" version of my website : http://19c50545d6.url-de-test.ws I'm using Polylang to provide english and french version of the website, and everything works fine with the desktop version of the website, but when i switch to mobile version, my mobile menu is empty : <div style="display: block; left: 0px;" class="sidr left" id="mobile-header-left-nav"></div> I checked that Polylang creates a main menu for each language, so i thought that it was the reason Cath Base couldn't find my main menu anymore, but as it works with the desktop version, i might be something else.... Any idea ? :) Regards, Patrick
