I encountered an issue with bp:FileUpload. When uploading a file, the upload fails with the error message “Missing CSRF token.” This issue was introduced in version 4.3.15 and did not occur in previous versions.
Sorry about that - we released DotVVM Business Pack 4.3.5, which fixes the issue, a week ago to our internal NuGet feed, but it wasn’t published on the customer feed.
It is there now.
Can you please try to upgrade the Business Pack to version 4.3.5?
