Error al publicar comentarios en post-template.
-
Hola a tod@s.
Recientemente instalé wordpress en un hosting gratuito. Todo funciona bien o eso creo, he ido probando widgets y plugins y hasta ahora todo ha «funcionado» correctamente dentro de los que cabe ( ha habido plugins y widgets que han dado sus correspondientes problemas).
Mi gran problema reside en los comentarios. Cuando intento publicar algun comentario en una entrada, me redirige a una pagina de error 404 diciendome que no se ha encontrado nada. Esto sucede cuando estoy logeado como administrador.
Si intento publicar algun comentario sin estar logueado, me aparecen estos 3 errores en la parte superior de la pagina.
Aqui os dejo los 3 errores y el codigo de mi archivo post-template.php
