A few posts won't load the editor. Other posts of the same post type work fine. See this video: hidden link The first 2 work fine, the 3th doesn't. Even if I disable all non-toolset plugins en switch to the default twenty twenty three theme.
If you duplicate the problematic post (using a plugin like 'Duplicate Post'), the problem also happens to the dupe page?
Moreover, could you please tell me the results of this investigation? Also, can you enable the debug mode? Just add the following code in your wp-config.php file:
// Enable WP_DEBUG mode
define( 'WP_DEBUG', true );
// Enable Debug logging to the /wp-content/debug.log file
define( 'WP_DEBUG_LOG', true );
// Disable display of errors and warnings
define( 'WP_DEBUG_DISPLAY', false );
@ini_set( 'display_errors', 0 );
// Use dev versions of core JS and CSS files (only needed if you are modifying these core files)
define( 'SCRIPT_DEBUG', true );
After adding the code above, try to reproduce the issue again and check if you'll find a debug.log file inside the wp-content folder. If you locate it there, kindly send us the last lines here in the ticket.
Duplicating the post works, I can edit it then. I can even publish it under the original URL... seems the old posts are corrupted for some reason, but this workaround is good enough is in this case. Thanks!
