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.
