Support » Plugin: Redis Object Cache » Redis diagnostic not working on new version

  • Resolved diegpl


    When I click on Redis diagnostic I get this message:
    <div class=”wp-die-message”><p>There has been a critical error on your website. Please check your site admin email inbox for instructions.</p><p>Learn more about debugging in WordPress.</p></div></body>

    Also, did we lose anything on this new version? I was testing the speed and I am feeling it is a little bit slower than before.

    Thank you!

    Can you check your PHP error log and post any errors that you see?

    I have set redis.conf loglevel from “warning” to “debug” and checked /etc/httpd/logs/error_log but did not see anything there. Should I check for the errors on another file? Tks.

    Try enabling WP’s debug log, that should write to wp-content/debug.log

    I found this in my logs,

    Update the dropin. Or deactivate the cache once and turn it back on. Not the plugin tho.
