Just see a blank page

Hi there,

I’ve developed a WordPress theme. Everything is okay but when I upload and activate this theme in shared host, I just see a blank page (I tested in localhost and is running really good). I tested in two others host, my own company host and HostGator and it’s return a blank page too. In my localhost, I turn apache to developer mode (display all errors) but I haven’t see any error. Just see in others server.

Now, I don’t wanna fix this bug. I just want to know how to display error same as every hosting provider. How to do that.

Thankyou for reading my topic.
