Hey John,

May i know where you see these 500 error with woff2 font? Because I tried to view your Easyblog and Easydiscuss page but i didn't see any warning or 500 error related this woff2 font.

If you saw this from the browser or your server error log, it could be your server didn't support woff2.

Try take a look following reference link how to set this up.

It is through the no response read I got from using this speed analysis tool...

Thanks for getting back to us quickly, I believe this issue most likely related with your webserver where it does not include woff2 inside the application server mime.

You can refer on my following URL here (under "APACHE: WOFF2 mime type" section) :

Perhaps you can consult with your webhosting service provider regarding on this and see how it goes?
