After network installing the Farm Theme Pack and activating the list of themes on Mysite, the themes become available at the site level. Once I select and activate the theme, the site goes blank, the dashboard goes blank, and every screen goes blank. I can't even look at the site dashboard to deactivate the theme.
How do I solve this issue and regain access to the site? I've network deactivated the theme on the Super Admin dashboard and still no luck.
Any help would be appreciated.
