installation issue
No route found for "GET /" after installing open source tag manager in my localhost (http://localhost/open-source-tag-manager-master/web/app_dev.php)
Your Apache configuration is incorrect, most probably rewrite rules don't work.
Make sure to:
a) Enable mod_rewrite (run "a2enmod rewrite" from command line)
b) In your virtualhost config, add a Directory directive as such:
<Directory /path/to/open-source-tag-manager/web> Options FollowSymLinks AllowOverride All </Directory>
In production, you might want to change this to be more secure, but try this to see if it works.
c) Comment out the "Header" directive in web/.htaccess, it causes errors (probably deprecated?)
d) Don't forget to restart Apache
