yes see my notes below
WP white screen
This is a very interesting article about WordPress White Screen. It is good to read it.
1) You must take a backup
2) you make the updates
3) if you have White Screen and YOU CAN, restore the site from the previous backup
4) if you can not restore you must and you are locked out of the site
- go to the wp-content/plugins and
- remove or rename the plugin that you added or
- rename the plugins to plugins1, then all plugins are going to be disabled
If you can log in or you are in step 3
or create a new dir plugin
or from the Admin Gui disable all plugins
Then try to move one plugin at a time to the new plugin dir
or activate one plugin at a time from Dashboard
Every time check if you have a White Screen.
The moment that you will see the White Screen. it will be a fraction of the time after the activation of the plugin that creates the conflict.
I hope to never have White Screen, but in case you have you must know the above.
