Thanks for the clarification. I believe the article itself is checked first, and then the issue -- that is, if the article's publication date falls within the user's expired subscription, they will still have access; and failing that, if the issue's publication date falls within the expired subscription range, then they have access. See classes/issue/issueAction.inc.php, around line 127. From the relevant bug report (http://pkp.sfu.ca/bugzilla/show_bug.cgi?id=2253
) this may need testing, and to be honest I haven't experimented yet; so if you find any issues, please let us know.
