Thanks for update! Installation on one server went as update without problem. On another it went trough as a new installation, I just uploaded dump file from back up and all is back and running.
Thank you again very much.
Note: Doug don't use IE there is another flaw and quite nasty - no fix yet. If you have apache on linux than the best is to install as follwing:
tar xvfz ISPConfig-2.2.29.tar.gz
