Hi @lostimagination,
Thank you for reaching out to us. I checked your setup and the first thing I noticed is that you’ve an outdated version of X and Cornerstone which could be causing the issue. Please ensure everything is up to date according to our version compatibility list at https://theme.co/docs/version-compatibility. Please follow the best practices when updating your theme and plugins. See https://theme.co/docs/product-updates for more details.
Upon further checking, I see you’ve cache enabled in your setup, please clear all caches including browser cache then deactivate your caching plugin and other optimization plugins. If you’re using a CDN, please clear the CDN’s cache and disable optimization services.
If the issue persists then please 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.
If nothing works then please follow this guide here https://www.wpbeginner.com/wp-tutorials/how-to-fix-the-link-you-followed-has-expired-error-in-wordpress/ and please have your host try increasing the following PHP settings to the specified value or to the maximum the web host can increase.
upload_max_filesize = 100M
post_max_size = 100M
set_time_limit = 5000s
max_allowed_packet = 16Mb
innodb_log_file_size = 128mb
And increase your allocated memory by adding this code in your wp-config.php (see https://theme.co/docs/how-to-increase-php-memory-limit)
define( 'WP_MEMORY_LIMIT', '256M' );
define( 'WP_MAX_MEMORY_LIMIT', '512M' );
Until your host adjust your configuration values, please have a look at the following article https://theme.co/docs/common-issues
Let us know how this goes!
