Adding CORS headers to EasyEngine


The Flatsome theme’s UX builder is not working and giving these errors :

So I want to add this in my configuration : Where should i add this code :


Wide-open CORS config for nginx

location / { if ($request_method = ‘OPTIONS’) { add_header ‘Access-Control-Allow-Origin’ ‘’; add_header ‘Access-Control-Allow-Methods’ ‘GET, POST, OPTIONS’; # # Custom headers and headers various browsers should be OK with but aren’t # add_header ‘Access-Control-Allow-Headers’ ‘DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range’; # # Tell client that this pre-flight info is valid for 20 days # add_header ‘Access-Control-Max-Age’ 1728000; add_header ‘Content-Type’ ‘text/plain charset=UTF-8’; add_header ‘Content-Length’ 0; return 204; } if ($request_method = ‘POST’) { add_header ‘Access-Control-Allow-Origin’ '’; add_header ‘Access-Control-Allow-Methods’ ‘GET, POST, OPTIONS’; add_header ‘Access-Control-Allow-Headers’ ‘DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range’; add_header ‘Access-Control-Expose-Headers’ ‘DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range’; } if ($request_method = ‘GET’) { add_header ‘Access-Control-Allow-Origin’ ‘*’; add_header ‘Access-Control-Allow-Methods’ ‘GET, POST, OPTIONS’; add_header ‘Access-Control-Allow-Headers’ ‘DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range’; add_header ‘Access-Control-Expose-Headers’ ‘DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range’; } }

Taken from here :


Issue resolved Done it myself.


Hi, I have same problem. could you please explain to me how you solved it?


CORS feature request has already been submitted a while ago on github repository. Have a look if you are interested:


Can you tell me how you were able to solve this and where exactly you put this code or in which files you did the modification?


Create a cors.conf file,put the above code in it and put it in that site’s nginx configuration folder.Test and Reload nginx


Which one is that specifically ?



/etc/nginx/sites-available ?


Somewhere else.

I added cors.conf in /etc/nginx

and tried out curl -s -D - -H “Origin:” -X OPTIONS -o /dev/null

but it seems that it didnt work.




Thanks will try.
