Bad Request Error 400 Google Drive

Hi,

Something should be logged in your PHP error log when you see the white-screen – please can you tell us what it is?

Also, setting WP_DEBUG in your wp-config.php to true may show it in the browser instead of a white screen.

Most likely cause is another plugin that uses Google services and which gets involved when it shouldn’t, when UD is trying to contact Google. Please de-activate any other plugins you have that use any Google services, and give it another try.

Best wishes,
David

I found the problem myself.
When you are logged in to too many Gmail accounts Google will just give error 400 pages when connecting to something.

You will need to perform the action on an incognito tab and all will be fixed.

This will not happen too often. We use Chrome OS computers in my company and you will very likely only encounter this if you are in a similar situation like me.
