Hello,
Please could you open dev tools with F12 button and check the errors? Screenshots are preffered.
Also, could you describe from what version you have upgraded and how (UI or PHP CLI, etc.).
Is there any errors in the data/logs?

Hello Maximus,

upgrade always from cli
.htaccess is same as GitHub
https let's encrypt
no error in log
no error in apache log
server : apache/nginx but no more info



step 1 : I am logoff .. and logo don't appear.. I look on the url of logo, and past and go directly ... "failled load ressource..... protocol error"
step 2 : on the stream, I have a attachment pdf.. when I click.. it's downloaded .. but look size ...
step 3 : on the stream, I have a attachment xlsx.. when I click .. it's open new windows.. with NSPOSIX....
step 4 : on the stream, I have a attachment docx ...... download begin but .. size.

same behaviour from document entity

but txt file is "opened" in a new windows without problem ! :s

Hello Team,
Maximus : find
on all file (Avatar.php, Download.php, Image.php, LogoImage.php) when I add :

        while (ob_get_level()) {
            ob_end_clean();
        } 

problem is solved.
Then I think, I must disable buffering somewhere (php.ini, nginx.config)
Is the documentation on GitHub about nginx is uptodate ?

Regards
