[Hustle] Hustle Pro return 403, when server returned cached page with Hummingbird Pro

Hi Support!

Today, an unexpected error was encountered.

I activated Hustle Pro, then cached page returned 403.

There is a possibility that the server environment may be the cause, so it can not be said to be a bug unconditionally.

But will you investigate the possibility of conflict between these two plugins?

I checked .htaccess etc, but I do not know the cause.

We will give you access to the site to provide server information, but please do not test on the site. Because 403 comes out …

As SnapShot Pro is installed, restore it in your environment and check it.

Thank you.
