 My server has open basedir restrictions.

 When editing a post on classical editor, on line 530, class-wp-editor
 checks for translations loaded for external TinyMCE 3.x plugins.

 {{{
  if ( @is_file( $path . 'en_dlg.js' ) ) { ..
 }}}
 On standard case , "@"supress the errors as it should.

 But I have, as many users,  my own error handling for pushing error logs
 in external collector.
 So "supress errors" @ seems to be non-effective;
 and my logs are full of these :

 "is_file(): open_basedir restriction in effect. File(/en_dlg.js) is not
 within the allowed path(s): (..) /wp/wp-includes/class-wp-
 editor.php","error_line":530

 The correct way to check a potential outside of openbasedir restriction
 seems to be

 {{{
  // Default error handler is required
     set_error_handler(null);

     // Clean last error info. You can do it using error_clean_last in PHP
 7.
     @trigger_error('__clean_error_info');

     // Testing...
     @file_exists($path);

     // Restore previous error handler
     restore_error_handler();
 }}}

 as to why '$path' seems to be '/' ,thus checking file at server root,  I
 have no clue ..
