With the new version of Joomla (1.5.2) I now have trouble installing some components using "Extensions/Install-Uninstall/Upload Package File". All I get is a white screen with no messages or errors. I did find a workaround though:

• FTP the file.tar.gz package file to a temp install directory on the server
• gunzip file.tar.gz
• tar -xvf file.tar
• Install using the ""Extensions/Install-Uninstall/Install from directory" instead
  • need to specify the full path to the uncompressed directory e.g.:/home/symmetricdesigns/public_html/install
