I have a big motherload of these error in the logfile - the backup is not uploaded to dropbox.
06:09:38 : A fatal error occured: The backup is having trouble uploading files to Dropbox, it has failed 10 times and is aborting the backup.
06:09:38 : Approximately 1% complete.
06:09:38 : Error uploading 'C:\inetpub\mysite.eu\chart.common.indicators.html' to Dropbox: Forbidden. Bad input parameter. Error message should indicate which one and why.
Is there any solution to these api call errors?
FYI: The installation runs on MS 2003 server / IIS6 with newest php and WP versions.
