I have the same issue. Just bought Paradise 1.4 and installed it on a fresh WordPress 3.6. This is the error I get:
Deprecated: Call-time pass-by-reference has been deprecated in /mnt/vol4/home/h/w/hwosco/public_html/wp-content/themes/paradise/functions/custom_types/sliders.php on line 123 Notice: add_custom_background is deprecated since version 3.4! Use add_theme_support( ‘custom-background’, $args ) instead. in /mnt/vol4/home/h/w/hwosco/public_html/wp-includes/functions.php on line 2871 Fatal error: Class ‘CustomAdminSubPage’ not found in /mnt/vol4/home/h/w/hwosco/public_html/wp-content/themes/paradise/functions/admin_options/AdminPageFactory.php on line 11
This is very urgent project for a client. Please send across a revised version of the theme.
