There are invalid characters detected in the document attributes in the nx.env file under the variable @NX_KEIT_AVAILABLE_FIELDS, the accent characters cannot be added in the nx.env or nx.env.tpl files.
i.e.  The errors captured in the log shows the word ‘T?TLE’ which is actually ‘TÍTLE’.

2. Then go to the administration tab->knowledge->documents->export/import->export/import template.
