@David te Kloese . It's still not work on Preview mode :(
When i open the file upload on Attachments it redirect to URL:
and it not work with URL :
It always get the message : "The resource you are looking for has been removed, had its name changed, or is temporarily unavailable." :(
In the "Settings" of URL and SEO, I checked in "Redirect page aliases to main URL". It's affect to the URL of the file upload?
It's any config i need to be change for define the URL of file upload?
