 * Hi,
 * I am using 750 network sites (Approx 66000 database tables) using WP version 
   4.2.6. Now I want to upgrade WP to latest version but when I try to upgrade the
   backend goes blank. Frontend is working fine but WP dashboard shows WSOD. Can
   anyone help me for the entire network upgrade. I have followed the default WP
   update steps. Also tried increasing memory limit, execution time, post max size
   etc.

 * Hi Gerald! Maybe you have already solved this, since it’s been a couple of weeks.
 * Wow! That’s a large network!
 * If you are still getting WSOD for the dashboard, I think I would start with deactivating
   all the plugins via ftp — just rename the plugins folder inside wp-content. Then
   try upgrading with them deactivated. Don’t forget to do the “upgrade network”
   step before reactivating.

 * Hi Bet,
 * Thank you for the response. I have tried with your way but still unable to upgrade
   the WP version. Might be issue occur due to database table. Can you suggest me
   another way. Thanks in advance.

 * Hi Gerald!
 *  So deactivating all the plug-ins didn’t let you update.
 * What sorts of themes are you using in the network? What sort of features might
   some of the themes have? Sometimes, themes can also have functions like plug-
   ins that can cause conflicts. I do understand with 750 sites that it’s not practical
   to deactivate all the themes. It’s something to check out though.
 * As a next step, I would enable WP-DEBUG, and try the update again. [http://codex.wordpress.org/WP_DEBUG](http://codex.wordpress.org/WP_DEBUG)(
   I would set debug true, log true, and display false.) That might give you a better
   idea of what sort of error you’re getting.

 * If you have wp-cli you can do the upgrade behind the scenes…
 * Are ALL dashboard pages blank or just the wp-admin for the main site or just 
   network admin?

 * If you’re getting the WSOD, your server logs would likely log the error in the
   site’s error logs which would state more specifically what the problem would 
   be and hopefully zero in quicker on the source.
 * Cheers!
