I have a problem after change my site server.
When i want to edit my custom post in admin, i get white screen after a few seconds loading. One of my custom field have the field type user and this load a lot of users. I’ve checked the problem, and when i delete this custom field i can edit the post, and it’s work great.
Also on the previous server works. It’s load very slow because i have 90 – 100.000 users, but it works.
I’ve checked the new server configuration and almost is the same ( memory limit and set time limit is greater ).
Is your post type hierarchical?
Since you’re getting a white screen and not a time out notice I would guess you’re exceeding the memory limit of the server.
turn on debugging on your site and you’ll be able to see what type of error you’re getting.
add to config.php
