Video Backgrounds not working on a Subsite in multisite install

[lifehouseglobal]

Hi there,

We’re running a Multisite install of WP. We have video backgrounds setup in the Pro builder and working nicely on the mother site. However when setting up the exact same way on a subset, the video won’t show. We have tested using the same video on both sites and same result. Mother site works, sub site does not.

Will put url’s in the secure note. Look forward to a response.

thanks
