Hello @aryanrajseo,
Thank you for providing the server response and the steps you’ve taken to troubleshoot the issue. To further assist you, I recommend enabling the Debug Log in WordPress. This will help us gather more information about the error and its cause.
Here are the steps to enable the Debug Log:
- Open the wp-config.php file located in the root of your WordPress installation.
- Find the line of code: define(‘WP_DEBUG’, false); and change it to: define(‘WP_DEBUG’, true);
- Add a new line below it: define(‘WP_DEBUG_LOG’, true);
- Save the changes to the wp-config.php file.
Once debugging is enabled, WordPress will start logging errors to a debug.log file in the wp-content folder. You can access this file using an FTP client or the file manager in your hosting control panel.
Please review the debug.log file and share any relevant errors or information you find. This will help us identify the root cause of the “Bad Request” error and provide you with a solution.
In the meantime, please ensure that you have the latest version of FluentSMTP installed and that all your plugins and themes are up to date. If the issue persists, please let me know and I’ll be happy to further assist you.
Thank you for your cooperation.
