Unable to edit page with Pro

[liamtuffrey]

Hi, I am unable to edit any of my pages with Pro. I am receiving this message on the screen when loading.

“The preview could not load. This is most often related to a plugin conflict or aggressive page cacheing. Checking the developer console for errors could indicate what went wrong.”

Hi There,

Thanks for writing in!
This might be due to several reasons.
I would like to suggest you few troubleshooting process to check if you the issue would resolved.

1. Ensure everything is up to date according to our version compatibility list at https://theme.co/apex/forum/t/troubleshooting-version-compatibility/195. Please follow the best practices when updating your theme and plugins. See https://theme.co/apex/forum/t/setup-updating-your-themes-and-plugins/62 for more details.
2. Clear all caches including browser cache then deactivate your caching plugins and other optimization plugins.
3. If you’re using a CDN, please clear the CDN’s cache and disable optimization services.
4. Test 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.
5. Remove custom CSS, Javascript and templates.
6. 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.
7. 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' );

In case the issue persists, would you mind providing us with login credentials so we can take a closer look? Please provide following information:
