...mi sta succedendo con diversi siti e diversi temi.
Le domande sarebbero:

1. è grave ai fini del posizionamento?
2. se sì, come risolvere (plugin?)
   Grazie!
   Hikari

Non è grave.

Grazie, un plugin in meno...:)
H.

Chiedo scusa se riapro questa discussione.
Nonostante non sia importante ai fini di posizionamento, avendo comunque lo stesso problema vorrei risolverlo e se possibile senza l'ausilio di plugin visto che si tratta di un sito wordpress.
Grazie a chi potrà darmi una mano...

Se non vuoi usare plugin devi modificare il tema che usi.

grazie della risposta Juanin.
Putroppo non capisco molto bene dove posso lavorare al codice. Mi potresti dare una dritta?
Grazie mille.

Beh dipende molto dal tuo tema.
Ogni tema è diverso quindi dovresti condividere il codice.

ok, se posso lo condivido (avrei bisogno di capire quale porzione di codice) altrimenti grazie comunque.

Il template di pagina dove ti tornano gli errori.

Ciao Juanin.
Forse ho capito dove andare a lavorare ma ti chiedo conferma.

Ecco il codice della pagina template che crea la visualizzazione del singolo l'articolo.
Grazie ancora.
