How to deploy symfony 2 application to hosting?

Question

symfony

Hello. There is a small symfony application on local hosting, it needs to be deployed to shared hosting. Unfortunately, I am unable to do this.
What I did:
Exported the database from the local server and imported it to the hosting server
Changed the database connection data in the /app/config/parameters.yml file
Renamed the web folder to public_html
Cleared the /app/cache/ folder
After all this, the server gives a 500 error.
Please tell me what am I doing wrong?

Answer 1

Many thanks to everyone who tried to help. The problem turned out to be so elementary. The hosting version was php 5.2. Changed to 5.4 and everything worked.

Answer 2

500th error is a sure sign to first look at the server logs.
