 * Hi there,
 * When I try to upload a file I get this error (after clicking “submit”):
 * Fatal error: Call to a member function setToken() on a non-object in /home/www/
   labs/standard/wp-content/plugins/simple-dropbox-upload-form/wp-dropbox.php on
   line 299
 * Any suggestions what may be going wrong here?
 * Thanks!

 * Do you have any other plugins that use DropBox?

 * Thanks for the quick reply.
 * No – I do not use another plugin that uses Dropbox.
 * I also tried different version of WP 3.4, 3.5 and 4.0. and get the same error.

 * Does any plugin on your site have the capability to connect to dropbox? I only
   ask because this is the error that is thrown when there is another plugin with
   the dropbox capabilities.

 * No – there was no other Dropbox plugin installed. I tested fresh installs of 
   WP with different version numbers (WP 3.4, 3.5 and 4.0.).
