    Hello,
    Activating the CSS/Js feature causes CORS errors. In my case this feature triggers some woff fonts processing. This is not fixable on client side. Maybe your end (cloudfront) needs optimization.

    *whitelist cors headers
    *add options with post, get.

    Thanks.

    Hi @hsntgm,

    Thank you for trying Optimole and contacting us.

    You can add this to your .htaccess and it should solve the issue:

    <FilesMatch ".(eot|otf|ttf|woff|woff2)"> Header always set Access-Control-Allow-Origin "*" </FilesMatch>

    Make sure to clear the cache from any caching plugins, this should solve your CORS error related to fonts.

    I hope it helps!

    Hi Vytis,

    Thanks for great plugin. This is a clean and simple solution to get rid of complex cloudfront interface.

    I’m on nginx and I have already applied the nginx equalish one to my server. Not working. So I suppose maybe your end has issue or tiny “always” option has big impact:)

    Thanks.

    Hi @hsntgm,

    Thank you for the confirmation but this shouldn’t be related to Optimole, it happens because of the strict content security policy on your website so no matter if it’s a resource loaded from Optimole’s CDN or any other external resource that is not your domain or not whitelisted on your website – you would be getting the same CORS errors so I would recommend checking with your hosting provider why the added lines do not work as expected as they can provide more insights.

    You are right I just realized that problem caused where fonts comes within css @font-face and cors headers cannot applied for these inlined css fonts. What a tricky thing.

    Thank you vytis.
