Why is it showing a white screen?

Question

PHP

I set up the CNC output of the complex news component, I met with the problem that when clicking on the link it shows a white page, I visited different ways to display errors that did not show anything. Also with the 404 page is also a white page

Answer 1

Because php error output is suppressed.

Answer 2

most likely problems with .htaccess. make sure that you have it configured correctly (and generally have it)
or, in a rarer case, a php error related to cnc.

Answer 3

To display PHP errors, add the directive to the .htaccess file:
php_value display_errors 1

Answer 4

check for the presence of the word return - a trifle, and sometimes it happens ...
