I’ve just started a standard LAMP DigitalOcean droplet and installed Google Pagespeed. The package is installed and listed in /etc/apache2/mods-enabled/
I have added the following items to the pagespeed.conf
ModPagespeedEnableFilters prioritize_critical_css
ModPagespeedEnableFilters lazyload_images,inline_preview_images,insert_image_dimensions
ModPagespeedEnableFilters resize_mobile_images,insert_image_dimensions
Which I have used on previous projects. For some reason none of these filters are being run. Inspecting the headers being passed from the server show no pagespeed headers.
I don’t seem to be running across any errors anywhere and I am stuck as to what to look for next.

It turns out it was the CMS I am using. It uses the register_shutdown_function from php which with a call back introduces no-pragma and breaks pagespeed
After enabling the mod with a2enmod pagespeed did you ensure that you restarted the apache process with service apache2 restart?
In some instances mod_expires is also required in order to use mod_pagespeed. It can be enabled with a2enmod expires; service apache2 restart
