Unable to view security announces

[madin...@yahoo.com.ar]

Hi.
When trying to read any security announce from the web site home page, I get 
error 403 and this message:
ForbiddenYou don't have permission to access /security/2019/dsa-4393 on this 
server.
Server unable to read htaccess file, denying access to be safe
Regards, Sebastián.
