Hi,
in the export files of the data cite export plugin, the locales for the licenses are not resolved, resulting in e.g.
#submission.license.cc.by4.footer##
This only happens if the Quick Submit Plugin is not installed. In the register function of the quick plugin, the locale LOCALE_COMPONENT_PKP_SUBMISSION is loaded and this function is called when exporting data with the DataCite Plugin.
Version: OJS 3.1.1
best,
Carola
