* Hi,
* I am attempting to get my browser caching to work and for some reason, it will
not work. I’ve SSH’ed into my server and enabled the expires module:
* ```
Loaded Modules:
core_module (static)
so_module (static)
watchdog_module (static)
http_module (static)
log_config_module (static)

reqtimeout_module (shared)
rewrite_module (shared)
setenvif_module (shared)
socache_shmcb_module (shared)
ssl_module (shared)
status_module (shared)
```
* From there, I went in and auto-enabled the plugin, which created this in my .
htaccess file:
* ```
# BEGIN WordPress

# dynamically generated, and should only be modified via WordPress filters.

Header set Cache-Control "max-age=31536000"
Header set Cache-Control "max-age=31536000"
# END WP-HUMMINGBIRD-CACHING
```
* From there, I cleared all my cache, enabled and disabled the caching, and still
no success. Does anyone have any advice?

* Hi [@activelightning](https://wordpress.org/support/users/activelightning/) ,
* Could we know what exact error message you notice in “Browser Caching” page under
Hummingbird > Caching > Browser Caching
* The code in .htaccess does look fine too. Could you please try clicking the “**
Re-Check Status**” button and then check whether it makes any difference?
* If you still have issues even after that then please do share a full-page screenshot
on what exactly you notice in “Browser Caching” page so that we could have a
better idea.
* Looking forward to your response.
* Kind Regards,
Nithin

* Hi Nithin,
* I’ve hit the recheck button and still have the same issue. You can find an attached
image of the error [here](https://ibb.co/7b6b7hB)
* In addition, this is the error in plain text:
Browser Caching is not working
properly:
* – Your server may not have the “expires” module enabled (mod_expires for Apache,
ngx_http_headers_module for NGINX)
– Another plugin may be interfering with
the configuration If re-checking and restarting does not resolve, please check
with your host or open a support ticket with us.
* Thanks for your help,
Andrew

* Hi [@activelightning](https://wordpress.org/support/users/activelightning/)
* Thanks for sharing a screenshot. Could you please check whether **zlib.output_compression**
is enabled or not?
* If not, to enable it, you can create php.ini file in the root directory and add
the following:
`zlib.output_compression = On`
* The root directory is where the wp-config.php file, /wp-content/, /wp-admin, /
wp-include folders reside.
* Once done please click the “Re-Check Status” button and then see whether it makes
any difference. Please do make sure to restart the server to ensure the changes
are reflected.
* Please do let us know how that goes.
* Kind Regards,
Nithin

* Hi,
* I’ve followed the instructions and did the restart to apache and nothing has
changed. I did create the php.ini file and put the line:
`zlib.output_compression
= On`
* Do you have additional ideas? The error message stays the same. I’ve activated/
deactivated, rechecked, and cleared my cache.
* Thanks,
Andrew

* Hello [@activelightning](https://wordpress.org/support/users/activelightning/),
* I’m sorry for the delay on our end, looks like we didn’t receive the email notification
for your last message.
* In this case, can you try a plugin conflict test? You can read about it here

* Hi [@activelightning](https://wordpress.org/support/users/activelightning/)
* Could you double-check if the mod_deflate is well configured?
* Scroll to configuration section:
[https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-mod_deflate-on-ubuntu-14-04](https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-mod_deflate-on-ubuntu-14-04)

* And if the local htaccess can override the Apache htaccess.
* Also, is it an Apache only server, or Nginx and Apache?

* I finally figured out the 4 cache expiry thing not working in hummingbird (they
always showed up yellow either disabled or false.
* The added caching code for some reason was not picked up wordpress when the code
is added to htaccess.
* To get it to work I had to move that code to my apache2.conf and then finally
everything lit up green.
* I read every single post on this issue in the top 10 google response and I can’t
beleive I didnt find it.

* Hi [@rjohnsonfbr1us](https://wordpress.org/support/users/rjohnsonfbr1us/)
* I’m happy to hear you found the issue.
* Yes, the apache2.conf need to allow the local htaccess to override the settings
to make it work, or place it directly on the apache file.
* I will go ahead and mark this ticket as resolved but feel free to let us know
if you have any further question.

* I’ve tried adding this directly to my apache conf file and it hasn’t done anything.
I still get the same error.

* Hi [@activelightning](https://wordpress.org/support/users/activelightning/),
* Browser Caching is a server side thing and Hummingbird tries to apply the required
rules but it still depends on the server to allow these rules to work and to
overwrite server settings.
* At this point I would suggest getting in touch with your hosting provider to
check this further for you and see why the rules are not working with their server
setup.
* Cheers,
Predrag
