For anyone who is facing this issue, its due to nginx configuration, you will need to add below line at least on the Site available/config file in root directory
# Symfony controllers
location /1750/your back office admin directory / { # [REQUIRED EDIT] the name of your admin directory
if (!-e $request_filename) {
rewrite ^/.*$ /1750/your back office admin directory /index.php last; # [REQUIRED EDIT] the name of your admin directory
}
}
dont forget to replace the "your back office admin directory " with link to your admin directory
this is fix the Symfony error which is a requirement for Translation and Debug
