"non-Pleskified" version of PHP as a handler

Im having problems installing wordpress.. Ive updated the server using this command /usr/local/psa/admin/bin/autoinstaller --install-component base --select-product-id plesk --select-release-current --reinstall-patch

But i am still getting this error!

ERROR: Call to undefined method PHosting_Apache::getPHPCliPath() (Adapter.php:134)

Any suggestions?
