Akeeba AdminTools Pro is displaying the error - Can't find stylesheet to import - see attached screenshot in Joomla Admin (Components | Akeeba Admin Tools for Joomla. This is brand new and I'm confused by it. Cassiopeia is installed, of course, and the RocketTheme Callisto template is the default template - and has been since the site was launched in 2005.
No other extension used shows this error and it's not displayed in any public-facing page.
Thanks.
