Support » Plugin: Post SMTP Mailer/Email Log » Invalid arguments passed to implode()

  • Hello,

    I have noticed the following PHP warning in debug.log:
    [03-Sep-2020 08:48:27 UTC] PHP Warning: implode(): Invalid arguments passed in wp-content/plugins/post-smtp/Postman/PostmanLogFields.php on line 63

    To resolve this, I add one check if json_decode() return an array before attempt to do implode, so replaced line 63:

    return implode( ',', json_decode( $json, true ) );

    with this:

                $json_array = json_decode( $json, true );
                if ( is_array($json_array) ) {
                    return implode( ',', $json_array );

    It’s an issue from one of the updates.

    1. you can enable log to screen check where the line is printed inside the log and delete the log rows next to the error.

    2. the all the mail entries.

    On the next logging, everything will be good.
