Image Carousel bug

At https://New-Energy-Declaration.net, right below “Founding Signatories,” I used the su_slider shortcode to place a slider with 9 photo images that was working for many years until recently. Now, the slides no longer auto-animate and, worse, clicking the arrow keys won’t change the slide! It remains stuck only on the 1st slide.

The shortcode I was always using for this, still on the page above, is –

[su_slider source=”media: 717,769,714,821,713,719,725,770,716″ limit=”13″ width=”650″ height=”200″ link=”custom” title=”no” pagination=”no” responsive=”no” centered=”no”]

This site runs an older version of WordPress, to maintain compatibility with a petitions plugin no longer updated. Recently, I upgraded Shortcodes Ultimate to the latest version. Checking, I saw that the slider is no longer working, though possible some other update caused the problem.

For testing purposes, I just created this page – https://new-energy-declaration.net/alt-front/ – where I implemented this new “Images Carousel” shortcode, which I understand should be used with the current version of Shortcodes Ultimate –

[su_image_carousel source=”media: 717,769,714,821,713,719,725,770,716″ limit=”20″ slides_style=”default” controls_style=”dark” crop=”none” columns=”1″ adaptive=”yes” spacing=”no” align=”center” max_width=”none” captions=”no” arrows=”yes” dots=”yes” link=”none” target=”blank” autoplay=”3″ speed=”medium” image_size=”full” outline=”yes” random=”no”]

Unfortunately, something about the shortcode above causes the page not to render at all!

Any idea how I can get images carousel working again? I’m willing to “go Pro” if needed to get the slider to work but, from the docs, looks like image carousels also work in the free version.
