Fatal error: Unknown: Cannot use output buffering in output buffering display ha (1 post)

    Hi there!

    Since upgrading to WP3.6, W3 and Code Insert Manager won't work well together.

    If i disable Minify, Database, Object and Browser caching, the problem goes away.

    Sometimes I get this error:
    Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0
    Sometimes the page shows a blank page, without any error, without any content.

    I've checked my host, it allows 256MB memory_limit for PHP.

    I've set my php.ini to limit to 128MB like this in PHP.ini:
    memory_limit = 128M ; Maximum amount of memory a script may consume (128MB)

    I´ve set the wp-config.php to:

    /** Increase memory limit for php to 128MB. */
    define('WP_MAX_MEMORY_LIMIT', '128M');

    I´ve optimized my DB, it's 14.076 MB now.
