Description:
r53416 changed the sourcetype from Url to web, UploadBase::createFromRequest uses this to determine which class to load
$className = 'UploadFrom' . $type;
There is no UploadFromweb class so null is returned to SpecialUpload so it spits you back to the upload form with no errors and no clue why it failed.
Version: 1.16.x
Severity: major
