 * hace unos días mi web se actualizó a la nueva versión de WordPress y desde entonces
   dejó de funcionar el administrador de wordpress.
    Intenté arreglarlo con ayuda
   en foros y ahora no me funciona mi web. sale este mensaje:
 * Fatal error: Call to undefined function untrailingslashit() in /home/o4f4lye4/
   public_html/wp-includes/option.php on line 136
 * ¿como puedo arreglar esto?
 * Gracias.

 * If this function is missing it means that something has not gone the right way,
   you have to proceed with the manual installation.
