I have this subdomain: https://butik.fitnessformularen.dk/wp-admin where i get this error when loading the header og footer builders:
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.
Origin URL: https://butik.fitnessformularen.dk
Preview URL: https://butik.fitnessformularen.dk
I have no caching plugins enabled. If you go to the domain https://butik.fitnessformularen.dk directly you will be redirected to the root domain. If you wan’t to see a page on the sub domain then go to: https://butik.fitnessformularen.dk/log-ind
Thanks!
