Why might web filter not work in Kerio Control?

Question

Computer networks

I installed Kerio, and transferred the backup from another computer on which Kerio 7.1.4 was installed for a Windows server. Why is the web filter not working? It is enabled and some components stopped working, namely in the "http Policy" tabs

Answer 1

Do you have any antivirus with active components for filtering traffic? And the second question - did it work before applying the backup?
