Subject: PHP files are not executing, showing blank
page

My Domain: ppdb-erlangga.ct.ws
My Username: if0_39856367

Problem Description:
My website is only showing a blank white page. I have
already uploaded all my files.

I have tried to debug this and found that PHP is not
running at all. I enabled display_errors in cPanel, but
no errors are shown. I also replaced my index.php file
with a simple test code: .
Even with this simple code, the page is still blank.

Could you please check the server configuration for my
account?

I can see the following error on your page:

Fatal error: Uncaught Error: Undefined constant "BASE_URL" in /home/vol2_5/infinityfree.com/if0_39856367/htdocs/templates/header.php:21
Stack trace:
#0 /home/vol2_5/infinityfree.com/if0_39856367/htdocs/index.php(1): include()
#1 {main}
thrown in /home/vol2_5/infinityfree.com/if0_39856367/htdocs/templates/header.php on line 21

So I’d say there’s something wrong with line 20 or 21 on your code
