Is it possible to make a slider with more than one value? In this case two, like this picture:

There is github.com/tpartner/LimeSurvey-Range-Slider-4x-5x , but it doesn't seem to work with version 5.4.3+220926. It just shows two text boxes for numerical input.

Did the question theme import correctly?

Do you see the question settings in the admin GUI?

Did you clear the assets cache?

Yes; yes; no, but I did that now. No help, still no slider.

It works for me with version 5.4.4.

Check for JS errors in the console.

Try setting debug to 1 and check the page source to see if the files below are present.

- rangeSlider.js
- rangeSlider.css

OK, that's it. rangeSlider.* are not seen in the page source.

debug=1 gives about 20 deprecation warnings, nothing more.

JS errors do not relate to this, I guess.

This page uses the non standard property “zoom”. Consider using calc() in the relevant property values, or using “transform” along with “transform-origin: 0 0”. 215544
JQMIGRATE: Migrate is installed, version 3.3.2 jquery-migrate-3.3.2.min.js:2:709
Layout was forced before the page was fully loaded. If stylesheets are not yet loaded this may cause a flash of unstyled content. jquery-3.5.1.min.js:2:81419

It's got to be something in your environment. I was able to successfully import the question theme and demo survey on a fresh 5.4.4 installation.

OK. What's you OS? I tried on Ubuntu 22.04.

Locally: Xampp, Apache, Windows.

Remote: Shared hosting, Apache, Windows.

But, I doubt its an OS issue. More likely something in the sever settings or possibly file permissions. (but I'm not a server expert)

Don't know what to test... Can you try this .lss, just to be sure, or send a working .lss to me?

I don't see your .lss.

Here is the .lss and the theme file I imported into my remote site.
