Fatal Error: DatacitePlugin Missing Method Implementations

[aalvan]

Hi everyone,

Description

I'm encountering a fatal error when trying to install the DataCite plugin in OJS.

Error Message

PHP Fatal error: Class APP\plugins\generic\datacite\DatacitePlugin contains 2 abstract methods and must therefore be declared abstract or implement the remaining methods (APP\plugins\IDoiRegistrationAgency::exportIssues, APP\plugins\IDoiRegistrationAgency::depositIssues) in /home/admin-usm/ojs/plugins/generic/datacite/DatacitePlugin.php on line 37

Environment

• OJS Version: 3.4.0.5
