After upgrade to 7.11.13, All - Email page is blank

In SuiteRM 7.11.13, the page of Emails (menu All - Emails) is blank. We use outbound email only, and this is working. Individual emails accessed through subpanels (DetailView) appear properly, as do the subpanel list entries seen in History. Logs (using Debug level) show only messages related to inbound email, which we are not using. Browser console log shows a couple of innocuous warnings but no errors. Iā€™m seeking to understand where else I might check to resolve (perhaps a specific SQL query?), or if this is a general issue seen by others.

Thanks, Sam
