Channels email record is not created

Hi There !

I’m getting this error…

Please help me to resolve this.

My Mautic version is: 2.15.3
My PHP version is: 5

Channels email record is not inserted
My problem is:

These errors are showing in the log:

Request URL: http://localhost/mautic/s/emails/new?mauticUserLastActive=1&mauticLastNotificationId=
Request Method: POST
Status Code: 403

Steps I have tried to fix the problem:

In Left menu, press in channels
Press in emails
Press in new
Fill the form
Press “Apply”
Nothing will be saved. All others featured works fine, this not.

Please Help me !

Thanks & Regards
