    I get lots of these when I turn on STCR logging. Seems to correlate closely to page hits. STCR seems to be working fine though. Just a bit worried something’s broken somewhere. zlib & zlib-devel are installed.

    [ERROR][2021-02-17 08:55:47] – An error occur, here is the detail information
    [ERROR][SEVERITY] – 8
    [ERROR][MESSAGE] – ob_end_flush(): failed to send buffer of zlib output compression (0)
    [ERROR][FILENAME] – /home/theeye1/public_html/xxxxx.org/wp-includes/functions.php
    [ERROR][LINE NUMBER] – 4755

    Hi @rufus-mcdufus

    The logger doesn’t log just the errors from our plugin, it intercepts and logs all errors.

    That error should mean the PHP function ob_end_flush() was called more times than needed. But we do not use that function in the plugin.

    It’s not an uncommon error. In case you’re not seeing any problems with the site functioning then don’t worry about it.

    And in case you do see problems with the site, give this a check.

    By the way, keep the logger disabled, it’s only for situations when a users runs into issues with the plugin, in which case the user would activate it to log the errors and we can access that log to figure out what might be the reason for an issue.

    Ah cool – I had a feeling the errors weren’t just from the plugin! I do normally keep the logger disabled – this was literally the first time I’d tried it.

    Thanks!
