OJS 3.1 QuickSubmitPlugin error

When I try to add an article, the plugin generates a blind screen and the log file generates an error:

PHP Fatal error: Call to undefined method PublishedArticleDAO::getPublishedArticleByArticleId() in /home/www/organizacja/zpub/public_html/plugins/importexport/quickSubmit/QuickSubmitForm.inc.php on line 67, referer: http://zpub.uek.krakow.pl/index.php/zpub/management/importexport/plugin/QuickSubmitPlugin

All directories have the appropriate permissions.

Can anyone help solve this problem?
Due to this mistake I can not transfer the publication to OJS 3.

Hi @lucien,

I suspect you’re using a version of the QuickSubmit plugin that’s not compatible with your version of OJS. What exact version of OJS are you using, and where did you get the QuickSubmit plugin from (the exact URL would help)?
