This Plugin works great for small backups that can be emailed or plain old insecure FTP. However, I am encountering numerous issues getting it working in a secure fashion with SFTP and laterly DropBox.
It may help narrow down outstanding issues if people stated what OS their WordPress is hosted on. My site is hosted on Windows. This issue did not arise when I tested the same version of this plugin on a Unix hosted site.
I am using version 1.7.1 of BackWPup- the latest version and experiencing the same issues with others eg:
[ERROR] DropBox API: Invalid signature. Expected signature base string: POST&https%3A%2F%2Fapi-content.dropbox.com%2F0%2Ffiles%2Fdropbox%2FBTOSCwordpress&file%3Dbackwpup_0_2011-03-29_19-08-52.zip%26oauth_consumer_key%XXXXauth_nonce%XXXXoauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1301422135%26oauth_token%3Devxxxx%26oauth_version%3D1.0
Can anyone suggest what changes I could make to the code that would help debug this?
