Helping work on a project and it is done via symfony2
Made some changes in twig and php files.
Not all of the changes took place.
Think the problem was that the cache need to be cleared so that the changes would take place.
Ran the following :
php ./app/console cache:clear --env=prod
After running it, I get now HTTP 500 on the dev site.
What happened and how can I figure out how to resolve the issue?
Im open to any advice and how to avoid the issue next time.
