If employees are not receiving approved leave notifications and are receiving rejected or cancelled leave applications, it could be because you have the wrong storage path set up in the system. Another scenario is if your manager approves the leave application, instead of getting a successful approval message, they get a blank screen. Please check your storage path as follows:
Go to EPE Control and click Modules.
Click Attachment Storage Configuration.
Log in to the company and update the Storage path to the correct location.
Ensure the storage path exists and is usable. You can create a specific folder in your server's C drive and point to it here.
