How to display pages in bitrix?

Question

PHP

The problem started when I started editing the "NanoCAD" page (screenshot 1) Then I
changed the page in the visual editor by simply deleting the "menu" component (screenshots 2 and 3)
blank white screen (screen 4).
I really need your advice

Answer 1

Well, you definitely shouldn’t do this through a visual editor) I deleted something superfluous. There is an item to edit in php-code mode - it's safer that way.

Answer 2

Go to the admin panel and open this file through it in PHP code mode. Find an error (remove something superfluous), fix it - and everything will be ok.

Answer 3

Enable debug
See header.php (is it the menu in the header?) for errors, for example <?php is opened and not closed and vice versa.
