... delete that string text from HEAD or from / HEAD ...
... for the correct procedures to perform are one of these (3) three listed, two (1), (2), via the program, and the third (3) via extra FTP (Filezilla, etc.) :

2) - >> Step 3 - Map > The Page Properties window| ▪Expert | ▪Custom Code | ▼Before closing the HEAD tag, ... paste:

3) - download the google file:

and send the file to the root of the site (extra FTP, Filezille, etc...);

(IT) - ... eliminare quella stringa ti testo da HEAD oppure da /HEAD...
... per le procedure corrette da eseguire sono una di queste (3) tre elencate, di dui due (1), (2), tramite il programma, e la terza (3) via FTP extra, (Filezilla, etc.):
1) - ▪Metatag per Google Search Console >> basta inserire il codice:
ZYX *** XYZ
2) - >> Passo 3 - Mappa > Finestra Proprietà Pagina > Sezione Esperto | ▪codice personalizzato | ▼ Prima della chiusura del tag HEAD, ... incollare:
<meta name = "google-site-verification" content = "ZYX *** XYZ" />
3) - scaricare il file google:
google12345 *** ect .html
e inviare il file alla radice del sito (FTP extra, Filezilla ect....);

Step 2 worked. Step 1 does not work - something happened when the project was updated from 13 to 14. The only way to fix the problem was step 2. If I leave step 1 in the SEO section then the error re-occurs.

Thanks
