# update-core.php doesn’t update

 * I’ve had this issue for the past several WP core updates. I go to the update 
   page, click update, and it says update complete but then splash page says “Welcome…”
   to the same version before updating and the message that an update is available
   remains. Folder ownership and permissions are correct. I have disabled all plugins
   and activated twentyseventeen theme. It happens in single site and multisite.
   It happens with or without cache plugins. I have cleared the browser cache. I
   have tried updating manually. It appears that the files have been updated but
   continue to get notices that an update is available and ../update-core.php never
   changes. I have scoured Google and WordPress forums. I’ve found nothing. What
   could cause this?
    Running Nginx on Ubuntu 14.04 with PHP 5.5.9. Any help or 
   insight would be much appreciated.

 * – Auto Updates can fail for a large number of different reasons and it is often
   hard to diagnose the failur0258520*/1 due to specific configurations present 
   on each server running the update. For example, permissions may be incorrectly
   set, the unpacking of the new version might not have been properly verified due
   to high system loads with your host if many users are updating at the same time
   or they have a very loaded service, An IO hang, files are being validity checked
   and they fail due to a corrupted bit. There are many more reasons that things
   could have failed. Honestly there’s no good way to track down why a partial update
   occurred, we can only recommend what to do if one does occur.
    – Hence try **
   MANUALLY** updating. [https://wordpress.org/support/topic/update-to-4-9-fatal-error-cannot-redeclare-get_shortcut_link/](https://wordpress.org/support/topic/update-to-4-9-fatal-error-cannot-redeclare-get_shortcut_link/)

 * I expected as much. I’ve tried manually updating multiple times. Thanks for replying.
   Carry on…
