Just setup a new server and have installed mod_pagespeed.

It only seems to be working on html pages, not PHP. Below are the headers for two simple pages and apart from the Vary: Accept-Encoding I can't see any differences. Can anyone help me to get this working?

Below is a php page where you can see pagespeed is not working

What does your serving path look like? Are html and php both served
from the same (apache) server?

If you request pages directly from your site, and not via cloudflare,
is it any different?

As a test I have created two files

example.html (contents of where are 1 line containing <h1>This is a test</h1>)
Headers received were 
HTTP/1.1 200 OK
Date: Thu, 29 Sep 2016 10:45:35 GMT
Server: Apache/2.4.18 (Ubuntu)
Accept-Ranges: bytes

X-Mod-Pagespeed: 1.11.33.2-0
Cache-Control: max-age=0, no-cache
Content-Length: 30
Content-Type: text/html; charset=utf-8
Which as you can see has page speed.

example.php (content of where are <?php echo '<h1>This is a test</h1>';?>)
Headers received were
HTTP/1.1 200 OK
Date: Thu, 29 Sep 2016 10:48:27 GMT
Server: Apache/2.4.18 (Ubuntu)
Cache-Control: max-age=0, no-cache
Content-Type: text/html; charset=UTF-8

No Pagespeed

Apache was a plain install, its running php7 and the same instance of apache serves both php and html. Everything is on one server. Turning off Cloudflare has no effect

Im completely stuck and Googling doesn't bring anything back, any help would be very much appreciated.

Can you paste your apache configuration, or at least the sections
handling php and pagespeed?

You have some apache configuration that sets up php, right? Does it look like:

<FilesMatch \.php$>
SetHandler application/x-httpd-php
</FilesMatch>

or something else?

There's something in your conf that I don't understand. With:

<FilesMatch "^\.ph(p[3457]?|t|tml|ps)$">
Require all denied
</FilesMatch>

It looks like apache should only be willing to serve files named:

*.php
*.php3
*.php4
*.php5
*.php6
*.php7
*.pht
*.phtml
*.phps

and it will reject all others. But you're saying it's serving html
files as well, which means there's something else in your conf that's
interacting with this.

The server was built from a base install of Ubuntu 16.04 from Digital Ocean. I added PHP etc. But yes its serving html and php.

Is there anything else I can check?

I'm going to need to see more of your configuration to understand
what's going on here. With the piece of configuration you showed me
apache shouldn't be able to serve html at all, yet it clearly is about
to do it, so there's some missing piece. Ideally that piece can show
why pagespeed isn't applying to your php files.

I've been trying to singe out what the issue is. I was using https://ismodpagespeedworking.com that website to check if page speed was working on two urls 


and it says no to both.

Inspecting the headers in Safari I can actually see "X-Mod-Pagespeed : 1.11.33.2-0" header present for both urls, whereas ismodpagespeedworking.com says it wasn't

For the main url http://www.thinkoptimised.com/ I can see that "X-Mod-Pagespeed : 1.11.33.2-0" isn't present. The only difference in the headers are the main url also sends "Pragma : no-cache"

Im going to guess this is the issue, but I haven't managed to find out how its being added yet. Do you think I am on the right track?

Weirdly I now see the X-Mod-Pagespeed: header for both your html and
php, while in your php example upthread I only saw the header on html.
So it looks like PageSpeed is working for you now.

Still, it's weird that it wasn't working earlier. I'm going to bring
up a test box with ubuntu 16, apache, pagespeed, and php, and see if I
can repro.

Ok, I set up the test server, and I see mod_pagespeed running for both
php and html files. Sorry!

One way to make sure PageSpeed is running is to append
?PageSpeedFilters=+debug to your html, look a the source, and scroll
all the way to the bottom. You should see debug comments confirming
that PageSpeed is enabled.

I still don't see it working on the main site. Only for the examples.

Im sure it has something to do with that Pragma?

So after a lot of digging I think its the CMS inserting the header. Im seeing if I can get an answer over there. 

Thanks for all the help Jeff
