I've switched from single site to multi-site and everything is running smoothly while pages are not working on sub-sites. I've created some test pages on sub-sites but when I try to access them it shows white screen of death? The front-end pages are working fine on super site but not on sub-sites.

Also WP_DEBUG_LOG and WP_DEBUG are set to true but still no error.

Any help would be much appreciated.


  • Enable debugging and report back. We may be able to help you, but it's also likely this question will be marked off-topic for being too localized/3rd party plugin. Let's see what you get first. Commented May 10, 2016 at 11:31
  • @TheDeadMedic WP_DEBUG is set to true but still it does not display any error nor it logs to a file neither error_log contains anything. Commented May 10, 2016 at 11:35
  • Have you tried WP_DEBUG_LOG as true as well as WP_DEBUG? Log file is in wp-content/debug.log. You might need to check the logs generated by apache/your server software (some environments might prevent WordPress from overriding error reporting settings) Commented May 10, 2016 at 11:37
  • @TheDeadMedic Both are set to true and I've doubled checked debug.log it does not contain anything. Commented May 10, 2016 at 11:40
  • Then you will need to check your server error logs - ask your host if you are unsure. Commented May 10, 2016 at 11:46

Try to set the WP_DEBUG constant to true in wp-config.php file to get any errors shown in your browser.
