Invalid token - cannot log in

[emiliaborowska]

From today, I cannot log in to contao manager of my website.

When I try to log in, the following appears:
Invalid request token!
The request token could not be verified. Please go back and try again.

This error occurres if there is a POST request without a valid authentication token. In Contao 2.10, the referer check has been replaced with a request token system. If the problem persists, you are maybe using an incompatible third-party extension or have not correctly updated your Contao installation.

For more information, visit the Contao FAQ page or search the Contao forum.

On the main page, the following code is visible:

What should I do? I do not have access to manager and cannot add any content.

Let me know please if there are any suggestions, any support from contao side?
