Why is the bitrix cnc white page displayed?

Question

1C-Bitrix

In the product catalog, when I put the CNC, a white page is displayed, absolutely empty, even with errors turned on, nothing is displayed. What could it be?

Answer 1

Found the solution! When, after setting up the NC, a white page begins to appear on all sections of the infoblock and elements, you need to go to urlrewrite.php and delete any rules regarding the infoblock where the error occurred! I personally erased one rule that seemed suspicious to me and everything returned to normal with me and nothing broke. I want to warn you right away that I don’t know if this can lead to bad consequences for you (you can save a piece of code elsewhere), but most likely you will just need to resave the cnc settings in the complex component where you configure the cnc and the urlrewrite.php file again will be generated in a normal state!
