php switch off doesn't restore Apache configuration

[dlange]

When switching to a php version and activating it for Apache everything works fine, however when turning it off again with "php switch off" it does not automatically restores the apache configuration.

Here the response when activating a php version for apache for the first time:

php switch php-5.2.10 -a
Use of uninitialized value $includedir in concatenation (.) or string at (eval 9) line 1.

    To: /usr/lib/apache2/modules/libphp5.so.system
Switching Apache2 module to php-5.2.10
You should restart apache2 using one of:
    - sudo /etc/init.d/apache2 restart
    - sudo service apache2 restart
    - sudo apachectl restart
