 * Hi [@sohani](https://wordpress.org/support/users/sohani/)
 * What’s the PHP version on your site? You can check it at the Help center > under
   Debug information:
    [https://smartslider.helpscoutdocs.com/article/1773-help-center](https://smartslider.helpscoutdocs.com/article/1773-help-center)
 * Do you see this error show up at your other sliders, or only at this one specific
   slider? Does the problem persists if you clear the slider’s cache? You can do
   that from the Slider Actions:
    [https://smartslider.helpscoutdocs.com/article/1764-slider-settings#slider-actions](https://smartslider.helpscoutdocs.com/article/1764-slider-settings#slider-actions)
 * Can you export the slider:
    [https://smartslider.helpscoutdocs.com/article/1728-export-import-slider#export](https://smartslider.helpscoutdocs.com/article/1728-export-import-slider#export)

 * I have cleared the cache, do I have to enable that button?
    there’s an instruction
   with a button that says,
 * Button ON/OFF (Delete resized image cache)
 * If enabled the following folder will be permanently deleted: /customers/6/9/7/

 * Hi,
 * I checked Smart Slider Free 3.5.1.9 on PHP 8.1.10 but I didn’t see this error
   or any other error connected to Smart Slider (even with `WP_DEBUG` enabled), 
   so I find it possible that it’s related to the displayed slider in some way.
 * Can you export the slider:
    [https://smartslider.helpscoutdocs.com/article/1728-export-import-slider#export](https://smartslider.helpscoutdocs.com/article/1728-export-import-slider#export)

   to see if we can reproduce the problem?
 * Also, can you try temporarily disabling your other plugings and switching back
   to a default WordPress theme (Twenty something) to see if the problem persists
   like that?

 * It’s fine if you leave it disabled. It only removed the resized images, but what
   this test needed to clear the slider’s cache, which is done without this button.

 * I see…
 * I tried exporting the slider, but it failed, I have shared the screenshot and
   website link in the support ticket
 * I have tried temporarily disabling the other plugins, the issue is with the smart
   slider

 * Hi [@sohani](https://wordpress.org/support/users/sohani/)
 * Since the issue is probably related to the slider itself (as I don’t see any 
   errors on PHP 8.1.10 on my test site) I really need the export file to figure
   out what’s going on.
 * Do you get any error when you try to export? Can you send me the exact error 
   message you get? If you wouldn’t get any error message, try to enable the error
   reporting on your server:
    [https://smartslider.helpscoutdocs.com/article/1949-error-reporting#error-wp](https://smartslider.helpscoutdocs.com/article/1949-error-reporting#error-wp)
   see if anything gets logged when you try the export. If any error happes, please
   send it to me.

 * Hi [@sohani](https://wordpress.org/support/users/sohani/)!
 * I wrote to your email yesterday, so it might have gone to your spam folder, if
   you haven’t received it. I will paste my answer here:
    “The problem with your
   slider is, that it was created with the Pro version of Smart Slider and Pro version
   sliders aren’t perfectly compatible with the Free version. Your slider has Pro
   background animations enabled, but currently you have the Free version of Smart
   Slider on your website, so when our code tries to find the selected animation,
   it can’t, and it produces the error you see. As you aren’t using the background
   animations at all, you could just go to your slider’s settings -> Animations 
   tab: [https://smartslider.helpscoutdocs.com/article/1779-slider-settings-animations](https://smartslider.helpscoutdocs.com/article/1779-slider-settings-animations)
   and X out the Background Animations. That should solve the problem!”
