We have (kind of) the same problem. We can not change/add images in the fullscreen slider in the layout builder. We already tried deactivating all of the installed plugins and even manually reinstalled the theme files but the problem persists. The error comes from the avia-media.js (line 107) -> “Uncaught TypeError: _.random is not a function”. Please check asap if you can find a solution. The customer for this website is already very impatient ;-)

Many thanks in advance!

Kind regards, Phil
