Pro Preview will not load

[jimmyp04]

I am trying to edit my page through the pro editor.
The only changes I made was updating the plugins, theme and wordpress.
I am currently getting this error:

1. I cleared the cache
2. cleared the style cache in X -> Settings
3. checked current PHP version (5.6)

Any ideas how to get this editor back? It worked fine before the updates. No new plugins or settings were changed.

Thanks

Hello There,

Please follow up the steps below:

1. Ensure everything is up to date according to our version compatibility list here. Please follow the best practices when updating your theme and plugins. Click here for more information.
2. Go to X > Settings and click on the Clear Style Cache button.
3. If you’re using a CDN(ex: CloudFlare), please clear the CDN’s cache and disable optimization services. For the CloudFlare you also need to follow the steps below besides the developer mode: https://xthemetips.com/using-cloudflare-rocket-loader-with-x-pro-and-x5/928/1
4. Test for a plugin conflict. You can do this by deactivating all third-party plugins, and see 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.
5. Remove custom CSS and Javascript from the options or Child Theme and test the case.
6. Switch to the parent theme to check if the issue persists.
7. Reset your htaccess file by renaming it to .htaccess-bak. Then in WP Admin Menu, go to Settings > Permalinks and just click the Save Changes button.
8. Make sure that you’re running at least PHP v5.6.x or later to avoid any WordPress related incompatibility issues. If you’re not sure what your server configurations and settings are, install a plugin like WP-Serverinfo (https://wordpress.org/plugins/wp-serverinfo/) and check your server info by head over to Dashboard -> WP Serverinfo area.
9. Check your PHP Max Execution Time and set it for 120 for optimal usage (https://thimpress.com/knowledge-base/how-to-increase-maximum-execution-time-for-wordpress-site/).
10. Increase the PHP Memory Limit of your server. Click here for more detailed information and how to increase the PHP memory limit.
