[Plugin: WP Super Cache] mod_rewrite rules stop gzip (5 posts)

    Hi folks,

    I have a problem with the WP Super Cache plugin: It seems to stop gzip from working.

    My hoster's Apache servers have the gzip module installed. All I had to do was to insert mod_gzip_on Yes in the htaccess file and several html compression checks indicated that my site was compressed.

    When I installed the WP Super Cache plugin, it stopped gzip. When I select chaching off in the settings gzip works. When I turn it on again, gzip stops.

    It seems that WP Cache Plugin mod_rewrite rules are the problem, as the message below reveals:

    Notice: PHP caching enabled but Supercache mod_rewrite rules detected. Cached files will be served using those rules. If your site is working ok please ignore this message or you can edit the .htaccess file in the root of your install and remove the SuperCache rules.

    Below are WP Super Cache mod_rewrite rules from the htaccess file. What do I have to do to make this work? Delete all of them? Or just some of them? And wouldn't that stop WP Super Cache from working properly?

    # BEGIN WPSuperCache
    <IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    #If you serve pages from behind a proxy you may want to change 'RewriteCond %{HTTPS} on' to something more sensible

    Remove that "mod_gzip_on Yes" line in the .htaccess file and use the compression in the plugin as it's better. It stores each cached page compressed already (and uncompressed for those clients that need it) so there's no need to gzip the page each time. mod_gzip compresses each time wasting CPU on identical pages.

    Thank you so much for your reply, I appreciate it.

    I deleted mod_gzip_on Yes from the htaccess file and tried to enable the compression in the plugin. The result: garbled text and weird characters all over the place. Need to hit refresh to load correctly. Something doesn't add up here, trying to find out more.

    And, thanks again for your support.

    Others have had this problem before. My htaccess file doesn't contain mod_deflate. And it seems zlib output_compression is on.

    zlib output compression is probably set in your php.ini so you'll have to be root to change that, probably. If you can't change it then you're out of luck. You'll have to disable compression in the plugin.
