Hi Rhonda,

I'm very sorry to hear that you're having difficulties activating LayerSlider.

This issue sounds very strange, we haven't encountered anything like this so far. What happens exactly when you click on the Activate button? Does the browser tries to navigate to the appropriate URL at all? 

If you're receiving a blank page, it indicates that there is a PHP error on your site. Enabling the WP Debug Mode can display the exact error message, which would be extremely helpful for us to provide a solution. You can also check the PHP error logs on the dashboard provided by your web server host, or just ask them to review the logs themselves and see if they can find anything. It's likely a web server configuration issue, so involving the host might be necessary.

Alternatively, we can also log in to your site and try to find what's wrong if you can provide us a temporary WP admin access. You can reply privately if you'd like to share credentials or other sensitive information.

This additional insight was really helpful and I now fully understand what's happening. It's almost certainly a JavaScript error that's likely caused by a 3rd party plugin. So it's a form of incompatibility. However, these are usually easy to catch and fix.

By temporarily disabling every other plugin (except LayerSlider) and switching to the default WP theme you can immediately rule out any chance of incompatibility. If this does not help, the issue you're experiencing is likely not related to other plugins/themes. However, if it does help, you are certainly ran into a compatibility issue. In that case, you can find out what's causing the trouble by re-enabling your plugins one at a time and watching when the issue returns. Since LayerSlider works okay with your theme on another site, it's probably a 3rd party plugin.

You can also check your browser's JavaScript console for any error as shown in this video (starting at 0:32). This is what we would check right away on your site when the issue is present. If you could share a screenshot of the console contents we could easily identify the issue.

Hi Anna,

It's likely something that the theme author can fix on their end. Usually the issue is that they load scripts and stylesheets globally. It can lead to certain issues when these assets are loaded unconditionally. Please check the JavaScript error console as mentioned previously and send the theme author a screenshot. You can also send it to us and we'll check whether we can provide a workaround from our side. 

Also, please open a separate ticket and continue the discussion there, so we won't spam the original ticket creator.
