HTML file lost style and picture after OJS3 upgrade

Hi,
I upgraded OJS from 2.8 to 3.0.2 and activated HTML Article Galley plugin.
If I click, as reader, on HTML button to read the published articles now I see plain HTML files without style.
I tried to add a css file in Settings > Website > Journal style sheet, but is useless.

From Chrome Developer Tool I see the link to my css

<link rel="stylesheet" href="http://myjournal.it/public/journals/4/styleSheet.css" type="text/css">

but is unable.

Moreover, all the links to the pictures of my articles are wrong: I cant’ see any picture in my HTMLs, just text.

Thank you.
Enzo

Hi @Enzo,

See e.g. OJS HTML articles.
