I'm on nginx, and i've configured nginx.conf via the tool.
On the front-end is all ok.
On the back-end i cannot insert images in contents.... via the image button in description text or via che button in the images and link section.
I receive "Forbidden. You do not have permission to access this document." error on the page.
And
GET /administrator/index.php?option=com_media&view=images&tmpl=component&asset=88&author=42&fieldid=jform_images_image_intro&ismoo=0&folder= HTTP/2.0
16385#0: *1477710 access forbidden by rule
on the server logs.
