Crossref plugin not working

[ctgraham]

This error message seems to be the same as the error you describe here:

PHP Fatal error

Hi Guys! I’m having trouble exporting plugin in a magazine specifically, follows the content of the error: mod_fcgid: stderr: PHP Fatal error: Call to a member function getPublished () on null in /home/sites/periodicos_home/public_html/ojs2/plugins/importexport/crossref/classes/DOIExportPlugin.inc.php on line 549 I researched some solutions in the forum, but did not succeed. Thanks!

Is the the same journal or a different journal which exhibits this problem?
