# mkdir_p triggering is_dir warning

 * On all my sites where I have WP Activity Log installed, the function mkdir_p 
   generates a warning due to the final “/” when recursing the log file location.
   
   This warning shows when logged in and it also shows with all the REST APIs, leading
   to broken JSON.
 * Here the error message:
    `Warning: is_dir(): open_basedir restriction in effect.
   File(/) is not within the allowed path(s): (/home/.sites/40/site933/web:/home/.
   sites/40/site933/tmp:/usr/share/pear:/usr/bin/php_safemode) in /home/.sites/40/
   site933/web/wp/wp-includes/functions.php on line 1974`
 * I temporarily fixed it by adding a while clause to skip also “/” (like “.”).
 * Not sure whether that’s a webspace setting, a plugin issue or just a combination.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fmkdir_p-triggering-is_dir-warning%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Something is misusing wp_mkdir_p() if the path/file `/` is being used in `is_dir()`.
   So likely a plugin. It’s normal for open_basesir setting to not allow `/`. The
   plugin doing this needs some modification. I think you know that modifying functions.
   php is not a valid fix.

 * Thanks for the answer.
    I have also connected with the plugin owner and they 
   are working on a fix. And yes, I am aware that modifying functions.php is not
   a sustainable solution. Though, does the trick until the plugin is fixed.
