If you are getting the following error when you are trying to start Apache:
Code:
Invalid command 'php_admin_flag', perhaps misspelled or defined by a module not included in the server configuration
Then you most likely have a misconfiguraiton in the php configuration file and the options.conf file.
To fix this, run the following as root:
Code:
./build all d
./build rewrite_confs
That should fix your issue.
