GZIP compression not supported by Wordpress 2.5+ (and what to do)
Tuesday, November 25th, 2008I noticed that the GZIP compression option was no longer there in Wordpress after version 2.5. This is recommended to be performed by the server now using mod_deflate.
If you don’t have access to mod_deflate, i.e. if you are on a uncooperative shared host, you can use this method using .htaccess …
Speed Up Your Blog Using ZLIB
If that doesn’t work you may be on a phpSuExec server. Create a file called php.ini in the root of your Wordpress install with the following contents …
zlib.output_compression = On
