For versions prior to 1.0.8 (included), you may experience problems with the Theme Options when you update to the Theme Classic.
To solve this problem you need to edit a theme php file to enable the ability to transfer options from one theme to another.
The procedure is as follows.
1) made a backup of the contents of your website
2) open this file /wp-content/themes/rexpansive-premium/admin/options-init.php located on your WordPress installation on your web server
3) go on the row 74, where you should see the following line
’show_import_export’ => FALSE,
this row will have to be modified in this way
’show_import_export’ => TRUE,
4) this change will enable in the Theme Options the Import / Export option
