Does not let Yii2 into the admin area of ​​the site?

Question

Yii

Tell me who understands Yii2. They gave the task to a man on the side, he jumped off suddenly. Now some miracles are happening in the project. Yesterday in the admin panel, today an error 403 was allowed. There is access to hosting. But with Yii, no one has ever worked
for us at such an address /panel/sign-in/login gives a 403 error
for this, we calmly go in /user/sign-in/login
What can be done?

Answer 1

Judging by your questions, you are unlikely to cope on your own.
If you need help with the project - write.
