I can't get rid of this message whenever I install a module, it shows:
User warning: The following module has moved within the file system: [modulename]. In order to fix this, clear caches or put the module back in its original location. For more information, see the documentation page. in _drupal_trigger_error_with_delayed_logging() (line 1138 of /data/all/000/core/drupal-7.54.2/includes/bootstrap.inc).
I read the documentation mentioned, but cannot find a module that could cause this.
What would be the right way to find the cause?
