I'm sysop on my wiki (2014.2 MLEB with MW 1.24.1) and I'm unable to undelete translations (whereas I'm able to undelete other articles in other namespaces).
Here is the error message: Permission error You do not have permission to view this page's deleted history, for the following reason: The action you have requested is limited to users in the group: Administrators.
Here is my user rights configuration:
require_once( "$LANG_EXT/Translate/Translate.php" );
$wgGroupPermissions['user']['translate'] = true;
$wgGroupPermissions['user']['translate-messagereview'] = true;
$wgGroupPermissions['user']['translate-groupreview'] = true;
$wgGroupPermissions['user']['translate-import'] = true;
$wgGroupPermissions['sysop']['pagetranslation'] = true;
$wgGroupPermissions['sysop']['translate-manage'] = true;
Is that a bug or a misconfiguration?
