I want to downgrade from my 2.2.4 to the actual 2.0.18.1 and found the downgrade script on this site. But when i try to download the downgrade.php file nothing happens. I use the following url for the script:

https://xoops.org/modules/core/singlefile.php?cid=4&lid=124

After clicking the ZIP icon the page changes to the download page and after three seconds it changes back to the startpage.
I tried it with Firefox and Internet Explorer, with Linux and Windows and asked other persons to try it. But it doesn't work. It seems, that the file doesn't exist anymore on the requested path.

Ciao,
Rainer
