Hi Tim,
I’m having the same issue than OP, and it started when I updated to latest version of wordpress last week (I’m running wordpress version 4.3.1 and Soliloquy Lite Version 2.4.0.3) On posts with multiple sliders, the top slider will show the first image and get stuck there. Subsequent sliders are stuck as if loading. (See: https://www.weareinhouse.com/portfolio/web-digital).
I updated the version of Soliloquy Lite, and then went back and checked the shortcodes. There’s not much else I’ve touched.
For the link above, here’s some screenshots of the images I’d expect to see from the top slider [ 1 ]
And for the second slider: [ 2 ]
