After Update Apache ist broken

after the last Apache update unable to start Apache

Failed to start service :

Starting web server: apache2Syntax error on line 39 of /etc/apache2/sites-enabled/XXXXXX.conf: Invalid command 'php_value', perhaps misspelled or defined by a module not included in the server configuration failed!

line 39 looks like this: php_value memory_limit +32M

even if I set this value to standart in Virtualmin Apache can not be restarted, rebooted the box but does not help either
