PHP warning while updating

  • Hello.

    I update Contact Form 7 from 5.5.3 to 5.5.4.

    The version of WordPress is 5.9.

    Both plugin and translation are updated well and form works well.

    But, I noticed that PHP warning has been shown as bellow.


    Warning: rename(/tmp/ja-［random character］.tmp,contact-form-7-5.5.4-ja.zip): Operation not permitted in /home/［installed folder of WordPress］/wp-admin/includes/file.php on line 1201

    Would someone tells me what does mean it ?
