    Hi Corey,

    While checking on other issues I now find I am getting these wp_debug messages constantly.

    They come in pairs with nothing between them as per below, and it seems they are compression related.

    Just curious, are they related to Cache Enabler, or something I have set wrong elsewhere, or is this perhaps related to the Fast Velocity Minify plugin?

    [01-Jul-2021 00:39:40 UTC] Zlib output compression ENABLED
[01-Jul-2021 00:39:40 UTC] GZhandler output buffer compression DISABLED
[01-Jul-2021 00:39:42 UTC] Zlib output compression ENABLED
[01-Jul-2021 00:39:42 UTC] GZhandler output buffer compression DISABLED

    Regards and thanks,
    Angus

    I notice that you have the Gzip compression setting enabled. If it occurs when a page cache is created then it sounds like it’s being thrown when a page is trying to be compressed. The messages themselves aren’t sent by Cache Enabler so I’m unsure of the exact origination.

    The “Zlib output compression ENABLED” log indicates that you have the zlib extension enabled, which compresses pages on the fly. I would recommend disabling this extension to make sure PHP is not compressing your pages in this way. One way to do this is setting the zlib.output_compression directive in your php.ini configuration file to Off: https://www.php.net/manual/en/zlib.configuration.php

    Hi Corey,

    Thanks so much. This is great advice and very helpful infomation.

    I shall read that manual as well as see if I can find who is using the Zlib.Gzip.

    Regards and thanks,
