[TYPO3-dev] TYPO3 Fatal Error: Extension key "backend" is NOT loaded!

[Franz Holzinger]

I have found out, that the file typo3conf/PackageStates.php has become 
empty after the deinstallation of an extension in the Extension Manager.


<?php
# PackageStates.php

# This file is maintained by Flow's package management. Although you can 
edit it
# manually, you should rather use the command line commands for 
maintaining packages.
# You'll find detailed information about the typo3.flow:package:* 
commands in their
# respective help screens.

# This file will be regenerated automatically if it doesn't exist. 
Deleting this file
# should, however, never become necessary if you use the package commands.

return array (
   'packages' =>
   array (
   ),
   'version' => 4,
)
  ?>

Some extensions have been listed here before. The EM did drop them all.
