White screen without errors

[diegomesia]

Good afternoon,

 

had a prestashop 1.4.8.2 working properly on a server and I had to migrate to another. Before I had it in OVH (Kemsirve) and now on amazon EC2. The fact is that when migrating stays blank screen and shows no errors. I tried to do everything:

 

- Check database connection (ok, connects)

- Enable display_errors

- Clear caches smarty

- Give permissions to any related folder (should not be done, I put 777)

- Clear .htaccess

...

 

In short, I used all the advice I read these two days I've been with the problem. I have other prestashop on this same server and operating properly. If you could see the error that, it could be correct ... someone comes up with something?

 

Thank you very much in advance.
