Can not edit through X Pro Builder

hi there,

i can not edit all my pages and header through X pro builder…

it said,
The preview could not load. This is most often related to a plugin conflict or aggressive page cacheing. Checking the developer console for errors could indicate what went wrong.

i checked the console and it said,
Response to preflight request doesn’t pass access control check: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘’ is therefore not allowed access.

can some one help me please?
thank you
