ALL sliders and header suddenly stopped working on my site

Hi, Enfold

Yesterday ALL sliders stopped working on my site. Actually, it’s only two sliders, but they’re both on the home page and are therefore extremely important. One is the fullwidth slider and the other is a partner slider just above the footer. Moreover, the header with the logo and menu have disappeared (appears only upon scrolling). So the entire home page is blank at first glance. I have absolutely no idea what is going on, since I have changed nothing (well, I did change one word in one of the slide captions–but that was a week ago) and these items had been working flawlessly for several months, update after update (No, I have not updated to the newest Enfold version released today, as I’d like to address this key problem first.)

Note that on all other pages of the site, the header is fine–but I use no sliders on those pages.

I’d appreciate a fix ASAP, as without the fullwidth slider and no menu–i.e., a blank home page–the site is effectively down.

I’m adding URL and credentials below in private.

Thanks!
