Revolution Slider not working or responding

[Omwoods]

This issue is on nancyjkelley.com - the slider is not working on the homepage, and I tried deleting and adding Revolution Slider again. Problem persists. I can see the Slider on the backend, but just get a dark grey background when I try to add or edit a slider - nothing happens, it doesn’t respond. I upgraded PHP to 7.2 just now but didn’t help. Increase memory to 256MB. I’d appreciate a link to download the plugin so I can install it via FTP separately. I saw that as a possible solution to this issue on another thread. Thank you!

I’m seeing something like this too:

		<script type="text/javascript">
			function revslider_showDoubleJqueryError(sliderID) {
				var errorMessage = "Revolution Slider Error: You have some jquery.js library include that comes after the revolution files js include.";
				errorMessage += "<br> This includes make eliminates the revolution slider libraries, and make it not work.";
				errorMessage += "<br><br> To fix it you can:<br>&nbsp;&nbsp;&nbsp; 1. In the Slider Settings -> Troubleshooting set option:  <strong><b>Put JS Includes To Body</b></strong> option to true.";
				errorMessage += "<br>&nbsp;&nbsp;&nbsp; 2. Find the double jquery.js include and remove it.";
				errorMessage = "<span style='font-size:16px;color:#BC0C06;'>" + errorMessage + "</span>";
					jQuery(sliderID).show().html(errorMessage);
			}
		</script>
		<script type='text/javascript' src='https://nancyjkelley.com/wp-includes/js/admin-bar.min.js?ver=5.0.6'></script>

Hey @Omwoods,

I checked the home page front-end and the slider is working.

The issue that I experienced was when editing the slider. The slider editor doesn’t load and here’s the error in the console:

Uncaught TypeError: Cannot set property 'cssText' of undefined
    at revolution.tools.min.js:44
    at Function.<anonymous> (revolution.tools.min.js:44)
    at s.check (revolution.tools.min.js:45)
    at new s (revolution.tools.min.js:45)

    at Array.<anonymous> (revolution.tools.min.js:44)
    at revolution.tools.min.js:46

Though Slider Revolution outputs the error message, the underlying cause is not actually Slider Revolution but highly likely third-party plugin conflict or even server related. You can see in the screenshot below that there’s a problem with WP load-scripts.php.

Please try testing for a plugin conflict. You can do this by deactivating all third party plugins, and seeing if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.

Also, contact your host to increase your allocated memory or do it yourself by adding this code in your wp-config.php.

define( 'WP_MEMORY_LIMIT', '256M' );
define( 'WP_MAX_MEMORY_LIMIT', '512M' );

We don’t have a link to download the previous version, regretfully. The only way is to revert your site if you have a backup.

Thanks.
