Bitrix - where did the authorization errors go?

Question

1C-Bitrix

Hello dear community.
There was a problem, authorization errors are not displayed on the site on Bitrix-Start.
Errors are not shown when calling bitrix:system.auth.authorizeor when access is closed in the section settings.
those. not on a custom authorization form template, not on a system one - it does not display errors, in case of correct login and password - it authorizes normally, in case of incorrect ones - it simply refreshes the page with the authorization form and that's it.
Ideas where to dig - ran out.

Answer 1

and in a call of a component there is a parameter?
"SHOW_ERRORS"=>"Y"

Answer 2

If the work is incorrect on the default template - you broke the core ))
The reason can be anything: deleted / changed language variables, deleted / changed the JS code of the core, the reason may even be in the rules for processing URLs. Lots of options. It is easier to reinstall the system or update all modules.
