Grazie per la replica.

Ho provato a mdificare il percorso così (scusami se mi muovo a piccoli passi):



codice:
@font-face {     font-family: 'KingthingsExeterRegular';    
 src: url('http://wp-content/themes/codium-child/font/Kingthings_Exeter-webfont.eot');     
src: url('http://wp-content/themes/codium-child/font/Kingthings_Exeter-webfont.eot?#iefix') format('embedded-opentype'),          
url('http://wp-content/themes/codium-child/font/Kingthings_Exeter-webfont.woff') format('woff'),          
url('http://wp-content/themes/codium-child/font/Kingthings_Exeter-webfont.ttf') format('truetype'),          
url('http://wp-content/themes/codium-child/font/Kingthings_Exeter-webfont.svg#KingthingsExeterRegular') format('svg');    
 font-weight: normal;     font-style: normal;  }
ma il comando non viene eseguito.
