AWS Lightsail w/ wordpress - Need to enable mod_expires - but can't find where

Keywords: WordPress - AWS - How to - Other
Just tweaking a cache plugin on my website and W3 Plugin support team recommend to enable mod_expires — Where and how I can do that…?

Thank You in Advance!

Hello @Artur,

To enable the mod_expires module you will need to edit the main Apache configuration file at /opt/bitnami/apache2/conf/httpd.conf and uncomment the line below so that it looks like this:

LoadModule expires_module modules/

And restart apache:

$ sudo /opt/bitnami/ restart apache

You can check the module is enabled running:

$ /opt/bitnami/apache2/bin/apachectl -M | grep expire

I go to


and do not see a

'LoadModule expires_module modules/'

I create this line and restarted my instance
Also when try to RUN your command for check

    '$ /opt/bitnami/apache2/bin/apachectl -M | grep expire expires_module (shared)'

I have some message command not found - please see attached image

Hello @Artur,

It is strange you do not have the expires_module line in the config file httpd.conf, could you check if it is present with this command:

$ cat /opt/bitnami/apache2/conf/httpd.conf | grep expires_module

That should output the line you need to uncomment.

Regarding the missing command, please try running the command without the initial $, as this is used to represent in written form that the line is a command to be run on a console. There is no need for the instance to be restarted, running the command to restart apache should suffice for the change to take effect.

Thank You for superfast response!
I do not know about the $ — I am sorry this command lines magic is new for me

When I go to my FTP I find 2 nd file and this line have this line for some reason I can fin this on published file but when run Your command now I see both of the comment and uncomment

see attached images

So this mines that this is working correct?

This backup file have this line - for some reason the published do not have
I just added and restarted

Hello @Artur,

Don’t worry about it! Yes, it seems the mod_expires module is now enabled in Apache.
