For instance your site is
www.example.com, the URL to the ubr_upload.pl should be
www.example.com/cgi-bin/uu/ubr_upload. If you try that URL in a broser you should get a page that says ERROR: Invalid parameters passed, that's a good sign.
If you get a 404 Not found error it means that the ubr_upload.pl was not uploaded to the correct location, and if you get a 500 Internal Server Error that means that the ownership and permission of the script are not correct.
Once the URL to the ubr_upload.pl works correctly, make sure that the same path is in General Settings -> Uploads -> URL to ubr_upload.pl
BTW, I tried to update to the latest hwd version, I'm running 2.1.2, and it couldn't find an xml file?
Probably you didn't tried the correct file. The main component is the com_hwdVideoShare_20091204.tar.gz file inside the Pro Package. Also make sure that you read and understand the tips at
documentation.hwdmediashare.co.uk/wiki/N..._hwdVideoShare_2.1.4
If you have problems with the upgrade please open a new thread.
