  • Hey there,

    WP Super Cache is causing troubles on two of my WordPress installations. On one the site just stops loading ( and the other one doesn’t load at all (
    I’ve turned the plugin off as an interim solution.

    What information do you need to resolve this bug?

    Thanks very much,

  • if you go into the advanced settings for wp super cache, and look for the “Compress pages” setting, uncheck that and it should begin working again. More information here:

    Zettt – You could also use the debug system in the plugin to figure out what the plugin is doing.

    You’re right! That actually helped. However though, after deactivating that option I have the problem that the settings page for WP Super Cache stays empty. If I disable mod_pagespeed everything’s back to normal.

    Got it. Somehow I had Legacy Caching activated. oO I don’t know why…always had mod_rewrite on. Seems like after re-enabling WP Super Cache it defaults back to Legacy.

    Sorry. That was wrong…

    I meant: Sorry, I was wrong. It didn’t help.

    I tried mod_pagespeed this morning and it broke my site when I had compression enabled. When I disabled compression in WP Super Cache and cleared the cache I was able to serve pages off my site.

    The pagespeed docs say that the mod doesn’t compress pages but it does seemingly load mod_deflate and compress pages. I don’t know if mod_pagespeed caches the compressed pages however.

    Right now, I’d say avoid mod_pagespeed and use wp-super-cache with compression, wp-minify to minify, and OSSDL CDN off linker to use a CDN if necessary.
