This is the second, and hopefully last, bug fix release of the 7.0 branch of Breadcrumb NavXT. In this release, the “Sorry, you are not allowed to access this page.” message when attempting to visit the Breadcrumb NavXT settings page has been fixed for the majority of users. Additionally, the behavior of the default setting instantiation was changed to allow bcn_settings_init to set the value of the following settings: Hhome_template, Hhome_template_unlinked, hseparator, and hseparator_higher_dim.
The permissions bug was due to the introduction of namespacing in adminKit 3.0, which caused a check against WP_Role to always return false (since it was looking in the wrong namespace), resulting in the bcn_manage_options capability never getting assigned to the administrator role. Note that this primarily affected sites that never had Breadcrumb NavXT 6.5.0 or 6.6.0 installed (i.e. new installs or updating from a version prior to 6.5.0). If your WordPress install does not have an administrator role, you will need to add the bcn_manage_options capability to the appropriate role in your install.
As always, you can grab the latest version of Breadcrumb NavXT from the Breadcrumb NavXT page.
