When using subdomains in Multi Site you might run into CORS related issues. To get around this, you should configure each site separately. Do the following:
– Go to the site’s own dashboard,
– Change OMGF’s cache directory ( Save font files to…) to something unique, e.g. /uploads/site1/omgf,
– Click ‘Save & Optimize’.
Repeat this for every site you want to use with OMGF. A new stylesheet, using the corresponding site’s Home-URL and cache directory for each font, will be generated. Bypassing any Cross-Origin Resource Sharing (CORS) issues you might run into.
