Hello,
It’s Redux plugin error related to PHP version. Open wp-content/plugins/redux-framework/redux-core/inc/classes/class-redux-functions-ex.php file, find
$data['parent_slug'] = end( explode( '/', end( $theme_paths ) ) ); $data['parent_slug'] = end( explode( '/', end( $theme_paths ) ) );
and replace with
$data['parent_slug'] = end( $theme_paths ); $data['parent_slug'] = explode( '/', $data['parent_slug'] ); $data['parent_slug'] = end( $data['parent_slug'] );
Regards
