[xwiki-users] Upload error (XWiki 4.0)

Today a user tried, but failed, to upload a document to our XWiki 4.0 It was an existing document, so XWiki should have created a new version. So I tried to upload the file myself, but... Uploading file to PAGE_NAME Message Failed to upload one file. Internal failure while attaching: NAME_OF_DOCUMENT: NullPointerException. Not a lot of info, clicking on the "NullPointerExceptio" does not reveal any more info. The PDF is only 9Mb...so that should not be a problem, right? -- View this message in context: http://xwiki.475771.n2.nabble.com/Upload-error-XWiki-4-0-tp7589754.html Sent from the XWiki- Users mailing list archive at Nabble.com.
