 * I am trying to see which plugins slow my site, and try to improve loading page.
   
   But after installed query monitor, I don’t have Queries by component, I only 
   have Queries by Caller
 * on the console got something like this “Extended query information such as the
   component and affected rows is not available. Query Monitor was unable to symlink
   its db.php file into place” Is this the error that caused the plugin can’t show
   queries by component ? How to fix ?

 * Yes that’s correct.
 * Did you click the “more information” link after the message? All the info you
   need should be on the page linked to from that message.

 * Well, it redirected me to here [https://github.com/johnbillion/query-monitor/wiki/db.php-Symlink](https://github.com/johnbillion/query-monitor/wiki/db.php-Symlink)
   
   I am not tech savvy so I don’t know what’s wrong. On fresh installed wp works
   fine, but on my production site got that error.
 * It seems like this solution is the easy way.
 * Relaxing the file permissions
 * Relax the file permissions on the wp-content directory and then de-activate and
   re-activate Query Monitor and it’ll attempt to create the symlink again.
 * Does that mean I just need to change folder permission on wp-content and reactivate
   the plugin ? what code for the permission ? 640 or something like that.
