Not sure if this is truly a bug but...
When I click on the "Admin Tools" icon on the Administrator page it opens a new page in browser with address:
[url=https://epesi.local//Admin]https://epesi.local//Admin[/url]
I receive error, "This webpage is not available"
When I type [url=http://epesi.local/admin]http://epesi.local/admin[/url] into browser address bar then it takes me to "Administrator's Tools" page without any error.
