# [Plugin: W3 Total Cache] zlib.output_compression

* I am getting the error at install saying:
* “Either the PHP configuration, Web Server configuration or a script somewhere
in your WordPress installation is has set zlib.output_compression to enabled.
Please locate and disable this setting to ensure proper HTTP compression management.”
* The thing is I did an ftp search on the individual site and the complete public_html
section of my hosting and came up with no results. I sent a support ticket but
would imagine others are getting the same error. Where do I find this compression
setting?
* Best,

* Well I made a info.php file and put it in the root of the public_html but I don’t
know what it does if anything. It has this in it:

* So what will that do?
* Still need some assistance.

* It displays some info about the php configuration to make sure that it has been
compiled with zlip.
Then, I would look at wp-config.php, .htaccess and the wp
settings page to see whether compression has been enabled elsewhere.

* nor any indication on the settings page … I think I may need a php.ini file to
override the server but I don’t know how to set that up and I don’t know if it
is the server. This site is hosted on namecheap hosting. They use cpanel

* Your server’s php.ini file is set to do compression and that setting needs to
be disabled. Please open a support with your hosting provider to rectify the
issue it should take a few minutes.

* My host is not so newbie friendly as they only use email for support. This is
from there “knowledgebase” :
* ////////////////////////////////////////
* How do I change PHP settings?
* You can manage all PHP settings with the help of your local php.ini file. To
use it you should just create a php.ini file under a folder with your PHP scripts
with the necessary PHP settings.
* For example, if you need to change the upload_max_filesize or register_globals
for one of your scripts under your public_html, you should create a php.ini file
under the folder with the following content:
* [PHP]
* upload_max_filesize = 8M
* register_globals = On
* //////////////////////////////////////////////////////
* Any place that I can find out how to do this php stuff while I wait for “support”?
* Thanks,

* OK it is fixed and working.
* Hey Frederick,
I was able to get my site fixed to work with the plugin. It was
an issue with the php.ini . All is well now. I went to put your link on my site
but I don’t like that I get this pop-up from your site. It says – xd_receiver.
htm – and if I let it load a file by that name loads into my temp folder but
the tab is blank. Not a good thing for visitors. I did put “Optimized by W3 Edge”
in my footer but will leave out the link for now.
* Best,
Leiif

I’m having the exact
same problem.

* Sorry satyre08 I didn’t get notice of your post. It has been a while and I just
messed it up again somehow. I think I tried a button in cpanel that says optimize
site. Now its all screwed up again. When I figure it out again I will post the
solution.
* Best,
Leiif
