I can't find where to change my slider's speed.

Is the slider part of your theme or is it a plugin?

It’s part of the theme. It’s a full-page background slider.

Your website isn’t accessible on my end. What theme are you using?

I can’t either all of a sudden. Drag.
I’m using this theme, which is also somehow inaccessible to me at the moment: https://www.web2feel.com/helix/?

Unfortunately the WordPress Community typically doesn’t support themes that are not from the theme repository. These themes are known to be insecure.

Anyway, because your website is offline it’s hard to help ??

Here’s a more direct link to the theme demo:
demo.fabthemes.com/helix

I’m using the same exact slider functionality as you see here, so I imagine the solution will also be identical.

The www.remarpro.com support forums are meant for the core application, themes and plugins that are distributed on www.remarpro.com. We do not support themes downloaded from elsewhere.

Thanks Esmi for reaffirming, I think we cross posted ??

@lastfewsteps: If you are 100% set on using that theme you could try contacting the publisher at https://www.fabthemes.com/contact/.

More information here: https://github.com/srobbin/jquery-backstretch

That is the actual slider documentation on github.
You need to set duration in milliseconds:

<script
  $(".foo").backstretch([
    "path/to/image.jpg",
    "path/to/image2.jpg",
    "path/to/image3.jpg"
  ], {duration: 4000});
</script>

Christian, you are the man.

Mods, thanks for letting me know about the Forum parameters. I’m relatively new to the forums, and I haven’t had a problem before.
