Having an issue after recent update to 7.4.1 from 7.4. Now when you send an email through Suitecrm originating in any of the modules and attempt to attach an existing internal document by clicking attach, then selecting add document, then the selector arrow which then displays an empty popup with the following in the title. crm/index.php?module=Emails&action=PopupDocuments&to_pdf=true&target=0.
All other pop ups and modules seem to work fine. Only seems to be an issue attaching internal documents.
