Ajax error with before after slider template from Slider Revolution

​I reinstalled my website, didn’t add any plugins but the slider keeps giving me an Ajax error when I attempt to add the template "before after slider"​

The error message shows as follows in Google Chrome Browser Dev Tool.
"Failed to load resource: the server responded with a status of 500 (Internal Server Error)"​

Slider’s Notification box just states “Ajax Error: Error”

What can I do to fix this issue, so I can utilize this specific template?

What I tried so far:
Increasing Memory Limit
Exporting template from one of my other sites since I have two licenses with you guys
Redownloading the admin-ajax.php file from my functioning site without that issue to see if it would fix it before I reinstalled wordpress on the domain.

I have Slider Revolution’s Latest Version 5.4.5.2 and X Pro’s Latest Version as well.

Hey,

I have checked your site and I cound`t find any ajax issue. I have created this page testing the slider and all looks normal.

Greetings John,

The slider works fine when I install other sliders but when I attempt with this particular slider that I need(see images) I get this error.

Hi There,

Unfortunately, premium templates is not available on the bundled revolution slider plugin. That’s the reason we can’t install it. With all the bundled plugins, we have the functionality of the plugin out of the box. Some plugins may lock features to purchases of the plugin that are verified by a license code on the WordPress install where the plugin is installed. However this is beyond our control. Thank you for understanding.

Hi Support,
I have the same problem but I don’t use a bundled version. Can you please assist.
Thx,
Matt
