Hi Chouby - thanks for your quick response.
All values in the admin theme options are filled (some with the default and some customized). File permission for wpml-config.xml is 0644 and the polylang folder 0755.
I also found the information in options.php and took it from there. The part you quoted is identical in the new version:
function optionsframework_option_name() {
$optionsframework_settings = get_option('optionsframework');
$optionsframework_settings['id'] = 'options_wpex_themes';
update_option('optionsframework', $optionsframework_settings);
}
You can check pastebin for the full options.php.
