    Hello @vmajor

    I am sorry about the issue you are experiencing and I am happy to assist you with this.
    Can you please share if you are on shared hosting? Are both Object Cache and Db Cache enabled using the Disk caching method?
    Thanks!

    Thank you for the quick reply.

    1. Server is a dedicated VPS
    2. Both Object Cache and DB Cache are cached with Redis running on localhost

    Hello @vmajor

    Thank you for the information.
    What is the PHP version you are using? Also, does the issue persist if you purge OC and DB cache?
    Thanks!

    PHP 7.2.24

    Yes it persisted through several cache purges. This is in this morning’s log along with system time. It only repeated 3 times today:

    Hello @vmajor

    Thank you for the information. We need to try and replicate this.
    You mentioned that you are running on localhost? Can you please share your website URL?
    Are you using Apache or IIS?
    Thanks!

    Sure: https://www.venn-cycling.com

    Apache.

    There is now around 60 entries in the log with the same three warnings.

    I looked up the originator IPs for the requests that caused these errors and they may in fact be attacks against your plugin which are failing because you changed the code.
