This log will provide us with specific file paths and line numbers, making it much easier to identify the source of the problem. * Please follow these steps to enable debugging and get the log file: 1. **Open your `wp-config.php` file:** This important file is located in the root directory of your WordPress installation. You can access it using an FTP client or through your hosting control panel’s file manager. 2. **Locate the debug line:** Look for the line of code that says: `define('WP_DEBUG', false);` 3. **Enable debugging:** Change the value from `false` to `true`. 4. **Enable log saving:** Immediately after that line, please insert a new line of code: `define('WP_DEBUG_LOG', true);` The resulting code block should look like this:`define('WP_DEBUG', true); define('WP_DEBUG_LOG', true);` 5. **Save the changes:** Ensure you save the updated `wp-config.php` file. * Once debugging is enabled and you’ve revisited the page where you’re seeing these errors (or any page on your site to trigger the errors again), WordPress will begin logging all errors and notices to a file named `debug.log`. * You will find this `debug.log` file inside your `wp-content` folder. A typical location would be: `/home/USER/public_html/wp-content/debug.log` (where `USER` is your hosting username). * Please share the contents of this `debug.log` file with us relevant to FluentSMTP. You can copy and paste the relevant parts directly into the ticket or upload the file to a service like Pastebin and provide the link. * **Important Note:** After you’ve obtained the `debug.log` and shared it with us, it’s highly recommended to disable debugging by reverting the changes in ` wp-config.php` (`define('WP_DEBUG', false);` and removing `define('WP_DEBUG_LOG', true);`). This is important for security reasons and to prevent the log file from growing unnecessarily large. * We’re here to help you get this sorted out smoothly! * [nwjeff](https://wordpress.org/support/users/nwjeff/) * (@nwjeff) * [3 months, 2 weeks ago](https://wordpress.org/support/topic/php-errors-342/#post-18831625) * I am seeing the same issue in the log file, how was this resolved?
