Jappix not show error

[tharhtet]

I created the jappix by using CentOS (Nginx) as a work space. Jappix didn't show anything. When i debugged the code inside server/functions.php, the function is not working. Is that server problem? Let me know php specification requirement and server requirement.

In Local Server, PHP function is working well. When i uploaded the jappix to digital ocean, the php doesn't work.

Eg.

<title> • </title>

In above code, _e() doesn't not work. Thank you so much.
