 * Hi,
 * Do you have the latest ThirstyAffiliates version (3.10.11) activated? If not,
   please update to 3.10.11 and see if that resolves the issue.

 * The message you are seeing is a warning not an error, so it shouldn’t cause any
   issues. Are you having any issues with ThirstyAffiliates functionality?
 * You can disable WP_DEBUG to hide the message from appearing.

 * I have the same problem and I am also using latest version.
 * Yes, it might only be a warning, but it is filling up my error_log very fast.
   In a week it is close to 1TB!

 * Is this warning due to PHP 8? My error log is getting bigger? Kindly fix the 
   warning ASAP.

 * Thank you for your patience while we got this fixed. We just released 3.10.12
   that adds checks so the warning won’t be generated. If you update to the latest
   version and still see the message, please contact us: [https://thirstyaffiliates.com/contact](https://thirstyaffiliates.com/contact)
