Blank page on the server

[eluser]Unknown[/eluser]
Hello, I'm having the following problem:

When I uploaded my project from localhost to the server, and I access to www.myserver.com I get a blank page (no error, even with the active log)

After hours of testing, I see that if I upload the project to a folder type www.myserver.com/test works perfect! ... but I can not get it to work (or at least see the error) in the root address (www.myserver.com)

Any idea what could be the problem?
Any idea as view errors?

Thank you!

very common problem.
find the error_log.
Where to find the error_log?
In the root folder of your site or CI.
Or in the CPanel.

Thanks Solid9!..

After hours and hours, I found the problem (I really stupid) .. a "small" die(); at the beginning of the first view. Sorry and thank you for your time.
