after update stopped working

Hi @nims

The problem on your site seems to be that for some reason some of our files contain outdated codes.

I find it possible that something went wrong during the update, and that is why some files weren’t updated properly. Try reinstalling Smart Slider:

and see if that helps.

Hi @nims

The /wp-content/plugins/smart-slider-3/Public/SmartSlider3/Application/Frontend/Assets/dist/smartslider.min.css file still loads the 3.4 version.

Can you check this file on your server, and see if it contains the following 3.4 code?
.n2-ss-slider .n2-ss-slide-background-image img{max-width:none;display:none;width:0;height:0}
The best would be checking it via a file manager or FTP, from your host’s side.
Then please try searching for:
.n2-ss-slider .n2-ss-slide-background-image img{width:100%!important;height:100%!
and tell me which search gave result.

What I suspect is that there’s some kind of caching (or maybe a server misconfiguration) that makes the server return the outdated version of the smartslider.min.css file and that causes your problem, because you’d need the up to date codes.

If you compare your own smartslider.min.css (https://www.yoursite.com/wp-content/plugins/smart-slider-3/Public/SmartSlider3/Application/Frontend/Assets/dist/smartslider.min.css)
file with the 3.4 version:
https://plugins.trac.ww.wp.xz.cn/browser/smart-slider-3/tags/3.4.1.17/Public/SmartSlider3/Application/Frontend/Assets/dist/smartslider.min.css
you’ll see that they’re identical.

But you’re using 3.5, so your smartslider.min.css file should be identical to the 3.5.0.9 version:
https://plugins.trac.ww.wp.xz.cn/browser/smart-slider-3/trunk/Public/SmartSlider3/Application/Frontend/Assets/dist/smartslider.min.css

You can use https://www.diffchecker.com/diff for the comparisons.

So, if your second search in the smartslider.min.css file gave result, that means the correct file exists on your server, but it’s not served by it. This can be due to a cache (probably a server side one), or a Cloudflare-like CDN service. If you have something like that, try clearing it.

If you don’t have such cache, then I suggest contacting your host with the link of the smartslider.min.css file (https://www.yoursite.com/wp-content/plugins/smart-slider-3/Public/SmartSlider3/Application/Frontend/Assets/dist/smartslider.min.css) and ask them why does the server load a different version of the file than what’s in the file system.
