Error: ActiongetCollectionInformation failed on error Forbidden

[PierreChambon]

I was getting errors
Error: ActiongetCollectionInformation failed on error Forbidden
Error: Actionwhoami failed on error Forbidden
Error: ActionloadConf failed on error Forbidden
When trying to access my brat server.

When running the troubleshooting script, I was getting the following message:
Received forbidden (403) when trying to access [brat_server_url]
Have you perhaps forgotten to enable execution of CGI in your web server configuration?

Adding the following line to my httpd.conf file (imported in apache2.conf file):
Options +ExecCGI
Fixed the problem.

This is how my httpd.conf file looks like now:

<Directory /var/www/html>
    AllowOverride Options Indexes FileInfo Limit
    AddType application/xhtml+xml .xhtml
    Options +ExecCGI
    AddType font/ttf .ttf
    # For CGI support
    AddHandler cgi-script .cgi
    # Comment out the line above and uncomment the line below for FastCGI
    #AddHandler fastcgi-script fcgi
</Directory>

#For FastCGI, Single user installs should be fine with anything over 8
#FastCgiConfig -maxProcesses 16

And of course then I reloaded with
sudo systemctl restart apache2

Hope it can help !
