Hi, after successful upgrade I have tried to export issues of one journal that we have to migrate to separate domain (idea was to upgrade current system with 15 journals to OJS 3.0.0 and then export issue by issue of specific journal to fresh install of OJS 3.0.0 which will host only that journal).
Export plugin take some time to process command but then it redirect to blank page, with error 500:
“NetworkError: 500 Internal Server Error - http://migracija.ff.uns.ac.rs/index.php/gff/management/importexport/plugin/NativeImportExportPlugin/exportIssues”
