I just wanted to mention, in case the solution is still pending, that I got the
[ERROR] DropBox API: (55) select/poll returned error
as well. I figured out what was causing it in my case. I had created a folder in my Dropbox called “WP Backup”. Apparently it did NOT like the space! I changed the folder name to WPBackup, and relinked to it as WPBackup/ in the folder box, and voila! it worked like a charm.
Thanks for such a great plugin!!
Thanks Netjera for spotting the space problem. Saved me hours of frustration.
Thanks to Daniel as well for a great plugin.
You’re welcome. :> I always try to post solutions or workarounds when I find them, hoping to save someone else some trouble. I’m glad it worked!
Hi, still getting this error for all Dropbox operations:
[ERROR] DropBox API: Invalid signature. Expected signature base string: POST&https%3A%2F%2Fapi-content.dropbox.com%2F0%2Ffiles%2Fdropbox%2Fburmablognet&file%3Dbackwpup_3_2011-04-19_05-35-13.zip%26oauth_consumer_key%3xxxxxxxxxx2%26oauth_nonce%3Dyyyyyyyyyyy%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3Dzzzzzzzzzzz%26oauth_token%3Dyyyyyyyyyyyyyy%26oauth_version%3D1.0
How to fix that “invalid signature”?
Downgrading to version 1.7.2 made Dropbox work for me.
@azega Thank you, that helped!
@netjera – Ran into the same error message and your suggestion came in handy. Thanks!
