403 Symfony网站的禁止错误

I uploaded my Symfony project to the public_html directory of the server.

The website address is: http://sta275.mit13.csesalford.com/surveywebsite/

All file permissions are set to 644, I've tried different combinations however I keep getting this error:

You don't have permission to access /surveywebsite/ on this server.

What I am doing wrong?

1.) Check your firewall settings to make sure that you don't have security enabled differently for production / development.

2.) Try running the application in development mode by going here: http://sta275.mit13.csesalford.com/surveywebsite/web/app_dev.php where you will see that you can access the app.

3.) Also try checking the log files located in /var/logs on the server. There may be clues in the there.

4.) It appears you can access the site in production mode by going to http://sta275.mit13.csesalford.com/surveywebsite/web/ also. This likely means there is a mis-configuration in your .htaccess file
