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.ww.wp.xz.cn/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!
