PHP

Gives error 500 and does not find
PHP classes Fatal error: Class 'app\\models\\vk\\ChatBotClass' not found in /var/www/..../SiteController.php on line 36, referer:
In principle, it is clear that backslashes are escaped somewhere, but I did not understand how to deal with this. I found this topic https://stackoverflow.com/questions/32083903/class... the solution is not clear. I would be grateful if anyone could explain.
I installed Yii2 from scratch, on the same server there is another application on yii2, there is no such problem, htaccess are identical

Answer 1

Messed up the class with namespace if anyone else runs into the same problem
