Plesk Error for installing typo3

[Hallomedien]

I want to install typo3 from the Plesk applications-button. First I get an multiulated installation page for typo3. Only the frist of 4 sections is readable und then there is an error message.

ERROR: PleskException Shortcut erstellenShortcut erstellenEine Ebene höherEine Ebene höher

Try to install latest typo3 packages using autoinstaller
or you can try to enable short_open_tag option (short_open_tag = On) in your /usr/local/psa/admin/conf/php.ini file
