Linux – Apache 2 Fails to Start After Upgrade with No Errors

apache-2.2debianlinux

Hoping someone can help me with a server issue. Recently we upgraded to the latest apache on 2 boxes within are organisation. One being the master box the other being for failover. The upgrade went fine on the master box but on the failover box apache fails to start with no errors, being output or logged. Both boxes have the exact same configuration so found this a bit strange.

I've reinstalled apache and have been through checking the configs and did not find any obvious errors. Eventally I ran a syntax check on each config file being included and found that one of the files apparently has syntax errors. 

Invalid command 'Order', perhaps misspelled or defined by a module not included in the server configuration

Invalid command 'php_value', perhaps misspelled or defined by a module not included in the server configuration

Invalid command 'GeoIPEnable', perhaps misspelled or defined by a module not included in the server configuration

I've trippled checked all the modules are enabled but it still fails. I've googled the subject of these errors loads but have been unable to fine a solution.

I was wondering if anyone had encountered such a problem before and could point me towards a solution.

Thanks for your help in advance.

It will be impossible to spot the error without the config files but you have some simple error somewhere in the configs. By simple, I mean something like a <Directory> or <VirtualHost> tag is missing in the config file. This is why it complains. For example, it sees : "Order deny,allow" out of context and reports an error about "Order". "apache2ctl configtest" will output a line number and file name you can use to pinpoint syntax errors.
