Installation server connection test no reaction - Javascript issue?

Hello,

I’m trying to install MODx 1.0.5. and clicking on "Test database server connection and view collations" nothing happens. There is an error message in the Javascript console:

window.addEvent is not a function
Quelldatei: http://www.allsense.org/modx/install/connection.js
Zeile: 1

There is a php info here: http://www.allsense.org/modx/phpinfo.php

Never hat this before, testet in Firefox and Chrome. No ad blockers or so activated ...

Thanks for any hints!

Your webserver is having trouble serving the following file for some reason:
http://www.allsense.org/modx/manager/media/script/mootools/mootools.js

Check permissions on it, and that the file is complete.

Thanks netProphET, that helped, I should have looked after files not found resp. not allowed.

That had been the case - The rights were on 740, dont’t know why, I thing 644 shoud be the right (Reading für public allowed).
