Hi @johnzapf!
I’m sorry about this. I checked out your website too and I still see some loading issues. What I currently see is, that one of your files:
https://cdn.jsdelivr.net/npm/d3@5/dist/d3.min.js
creates a bigger delay during the loading of your page:
https://www.dropbox.com/s/6s8sf2sakdh4vxv/delay.PNG?dl=0
and this holds off the images of the slider. What I see is, that this JavaScript is delayed on purpose by WP Rocket, probably by its “Delay JavaScript execution” option. This option makes your codes run at a later time, so please try to turn it off and check again. If you need to update Smart Slider to see the problem, do that first. If you still see an issue, try to turn off WP Rocket all together, to pinpoint if the problem happens due to one of their settings or not.
If you would still have a problem after this, we are really not allowed to support the Pro version of Smart Slider in these forums, so please rather write to us through our support form, and we will help further!
