Getting "This document could not be checked out to your local drafts folder. The document may have already been checked out, or the local drafts folder could not be written to." when trying to checkout a document
In this case customer was getting the following error when he was trying to checkout a document
"This document could not be checked out to your local drafts folder. The document may have already been checked out, or the local drafts folder could not be written to."
Interestingly this issue did not occur on a new web application, and we did not see anything strange in ULS logs either.
This was also an issue caused by the WebDAV module, interestingly customer had this WebDAV module installed for only one web application which kind of explain why the issue was occurring on only one web application
