Centos 6.7 + openfire 4.0.1

As result all roster looking as offline

HDD space not full , inode limit good too

On debian working good , but cant use user export/import plugin for transfer

When try import fresh .xml got error “The import file does not match the user schema.”

Can provide any log

Will apreciate for help
