Uncaught TypeError: Cannot read properties of undefined (reading ‘data’)

We are experiencing the same issue. Have you had any luck resolving this?

Hello @10gital,

Thank you for reporting this issue. I understand that you are experiencing an error when trying to resend failed mails from the logs page.

I have done some research and found that FluentSMTP is working fine on our end. To proceed with further investigation, you can try enabling debugging in WordPress. Here’s how:

1. Open the wp-config.php file located in the root of your WordPress installation.
2. Find the line define(‘WP_DEBUG’, false); and change the false to true.
3. Add a new line below it: define(‘WP_DEBUG_LOG’, true);
4. Save the changes.

This will enable WordPress to log all errors and other debugging information to a debug.log file in the wp-content folder. You can then access this file using an FTP client or the file manager in your hosting control panel.

Once you have enabled debugging, try resending the failed mails again. If the error persists, please provide me with the contents of the debug.log file.

I hope this helps!

Hi, I changed PHP 8.3 to PHP 8.2 and the issue disappeared.

Hello @10gital,

Thank you for the update. The issue you are experiencing is most likely caused by the compatibility issue with the latest version of PHP. I understand that you have already tried switching to a lower version and the issue disappeared.

I will forward the details of this issue to our team. In the meantime, I would suggest continuing to use the lower version of PHP. Once a compatible update is available, I will notify you.

If you have any other questions, please do not hesitate to ask.
