403 Forbidden in FreePBX UCP

[coobic]

@GameGamer43, many thanks for answer.
Version of UCP is 12.0.9, i`m include ChromeLogger to UCP for PHP debugging and see strange issues (UCP_login_token sometimes null and sometimes differ from token in POST).
I will try to update to latest 12.0.11 tomorrow, but i want to find root cause of 403 for my ‘php’ knowledges.

Also as you are developing a custom module, ensure you are using pjax within UCP or you can end up with issues like what you are describing.

Yes, i`m using pjax (‘data-pjax’ and custom handlers for my classes) - it work perfectly.
