I have to say at once that I am no expert, so apologies for asking for your help as follows:
I have been using "Celtic (Plain):001.001" font on a Wordpress website for several years without any problems.
Now there is a problem - on inspecting the website there is an error telling me this: "downloadable font: download failed (font-family: "Celtic (Plain):001.001" style:normal weight:400 stretch:100 src index:2): bad URI or cross-site access not allowed source: https://xxxxx/wp-content/themes/responsive-childtheme-master/fonts/Celtic.ttf"
In my child theme's stylesheet I have this: "@font-face {font-family:"Celtic (Plain):001.001";src:url("https://xxxx/wp-content/themes/responsive-childtheme-master/fonts/Celtic.eot?") format("eot"),url("https://xxxx/wp-content/themes/responsive-childtheme-master/fonts/Celtic.woff") format("woff"),url("https://xxxx//wp-content/themes/responsive-childtheme-master/fonts/Celtic.ttf") format("truetype"),url("https://xxxxx/wp-content/themes/responsive-childtheme-master/fonts/Celtic.svg#Celtic") format("svg");font-weight:normal;font-style:normal;}"
In my fonts folder I have these fonts: Celtic.eot, Celtic.svg, Celtic.ttf, Celtic.woff.
I have this error on one website. I also have another testing Wordpress website elsewhere and there is no problem with the font.
So I am not sure if this is due to the way I installed the font or CORS policy scripting.
I saw a similar topic here eot, woff fonts - I assume this is not the same thing?
I sincerely hope you will be able to help. Thanks in advance
This was resolved by my host provider - there was a setting that was not configured on their panel for the CORS rule to work.
