Hi @alivanrental!
I think your problem will be given by the JavaScript errors of your website. The way JavaScript errors are working is, that they are stopping all JavaScript codes following them. You can see these errors for example in Chrome if you press F12 -> click on Console -> refresh the page. Currently if I look for example on this page, where you have a Smart Slider too:
https://www.busrentdubai.ae/bus-rent-dubai-services/
I can see multiple JavaScript errors not related to our codes. I don’t see JavaScript combination/minification being used, but I do see that besides the 1st error, the rest is caused by some of WP Rocket’s optimization codes, because the way WP Rocket works is, that if you enter any parameter into the url, that page won’t be using WP Rocket anymore:
https://www.busrentdubai.ae/bus-rent-dubai-services/?1
and the errors aren’t happening on that page.
So right now the slider loads fine on that page (even on the WP Rocket version), because our codes are happening before these errors. When you use the JavaScript combination, all js codes are getting into one file, so the order of codes are changing. This is why we could get behind the errors, where codes cannot work any longer. You would need to resolve these errors, if you want to use WP Rocket without creating issues. The first error is connected to some “HappyForms” codes, while the 2nd and 3rd possibly connected to Contact form 7 plugin. If after resolving these errors you would still have a problem with our slider while using JavaScript combine, then please contact us here:
