 * I don’t know if this is a general issue, or something to do with my set up, however
   the plug appears to breaking the /wp-admin/edit.php page with WordPress 4.9.
 * Just getting a blank page, with the plugin deactivated, the page shows up as 
   expected.

 * Hi there,
 * We’re sorry to hear that you have some issues with our plugin, so please let 
   me try to help you. Can you provide us with any details of the error? Having 
   a white screen probably means that there was an internal server error and there
   should be a log of that stored on your hosting environment. Please send the information
   to [support@admincolumns.com](https://wordpress.org/support/topic/wordpress-4-9-2/support@admincolumns.com?output_format=md)
   so we have a look at it.

 * Thanks for the update. I cannot reproduce this issue on a fresh install. Did 
   you do a fresh install of the plugin of did you update form an earlier version?
   In case of an update, can you tell me how you updated the plugin?
