Hi @hardi,

As the error message says, the file lib/pkp/plugins/importexport/native/filter/NativeExportFilter.inc.php is missing from your installation. Download the .tar.gz package for the same version of OJS and get that file from it.

OK @asmecher thank you for your advice. I’ve already copy native folders and its works.
