Editing original post: When I click "Print Report" from a case, the page is not pulling the CSS and activities are not showing. After the page reloads, I receive an error:
Warning: DOMDocument::loadXML(): Empty string supplied as input in CRM_Case_Audit_Audit->getActivities() (line 33 of
C:\xampp\htdocs\sites\all\modules\civicrm\CRM\Case\Audit\Audit.php).
Originally, the conversation on Mattermost lead to a suspicion that this might be a Windows server issue. It's unclear now, but I do see this issue occur in both of my CiviCRM on Xampp windows. In Linux, I don't have this problem.
Has anyone received this error before?
