I can see this happening only in imported articles when using the (cur) (last) links. Otherwise, it looks like the error would be valid. To fix the (cur) (last) in imported articles, edit vault/functions/history.php. Find:

Code:

ORDER BY revisionid $sortorder

Replace with:

Code:

ORDER BY dateline $sortorder

This did not resolve it. Please see the other report.

Got it. When using the next/prev keywords, VaultWiki was trying to resolve the keyword using the known revision ID as a reference, rather than the known ID's edit-time. In imported wikis, the IDs are not necessarily in time order, so this caused issues when the reference edit had the highest or lowest ID for a given article.

In vault/functions/history.php, find:

Code:

		$fetch_revisionid = $db->query_first_slave("
			SELECT revisionid
			FROM " . TABLE_PREFIX . "vault_revision
			WHERE threadid = " . intval($threadinfo['threadid']) . "
				AND revisionid $sign $revisionid
				" . (!$canrollback ? "AND pending = 0" : "") . "
			ORDER BY revisionid $sortorder
			LIMIT 1
		");

Replace with:

Code:

		$ref = $db->query_first_slave("
			SELECT dateline
			FROM " . TABLE_PREFIX . "vault_revision
			WHERE revisionid = " . intval($revisionid) . "
			LIMIT 1
		");

		$fetch_revisionid = $db->query_first_slave("
			SELECT revisionid
			FROM " . TABLE_PREFIX . "vault_revision
			WHERE threadid = " . intval($threadinfo['threadid']) . "
				AND dateline $sign " . intval($ref['dateline']) . "
				" . (!$canrollback ? "AND pending = 0" : "") . "
			ORDER BY dateline $sortorder
			LIMIT 1
		");

Find:

Code:

	if ($direction != '')
	{
		if ($direction == 'next')
		{
			$sign = '>';
			$sortorder = 'ASC';
		}
		else if ($direction == 'prev')
		{
			$sign = '<';
			$sortorder = 'DESC';
		}
	}
	else
	{
		$sign = '=';
		$sortorder = 'ASC';
	}

	$revision = $db->query_first_slave("
		SELECT revision.*, user.username
			$hook_query_fields
		FROM " . TABLE_PREFIX . "vault_revision AS revision
		LEFT JOIN " . TABLE_PREFIX . "user AS user ON (revision.userid = user.userid)
		$hook_query_joins
		WHERE revision.revisionid $sign " . intval($revisionid) . "
			AND revision.threadid = " . intval($threadinfo['threadid']) . "
			" . (!$canrollback ? "AND revision.pending = 0" : "") . "
		ORDER BY revision.dateline $sortorder
	");

Replace with:

Code:

	if ($direction != '')
	{
		if ($direction == 'next')
		{
			$sign = '>';
			$sortorder = 'ASC';
		}
		else if ($direction == 'prev')
		{
			$sign = '<';
			$sortorder = 'DESC';
		}

		$ref = $db->query_first_slave("
			SELECT dateline
			FROM " . TABLE_PREFIX . "vault_revision
			WHERE revisionid = " . intval($revisionid) . "
			LIMIT 1
		");

		$hook_query_where = "dateline $sign " . intval($ref['dateline']);
	}
	else
	{
		$sortorder = 'ASC';
		$hook_query_where = "revisionid = " . intval($revisionid);
	}

	$revision = $db->query_first_slave("
		SELECT revision.*, user.username
			$hook_query_fields
		FROM " . TABLE_PREFIX . "vault_revision AS revision
		LEFT JOIN " . TABLE_PREFIX . "user AS user ON (revision.userid = user.userid)
		$hook_query_joins
		WHERE revision.$hook_query_where
			AND revision.threadid = " . intval($threadinfo['threadid']) . "
			" . (!$canrollback ? "AND revision.pending = 0" : "") . "
		ORDER BY revision.dateline $sortorder
		LIMIT 1
	");
