Symptoms

1. You are providing backup service based on Acronis Cyber Protect Cloud through WHMCS.
2. You create a backup plan for selling.
3. You select Recurring Payment in Product Properties -> Pricing.
4. Your customer purchases backup service.
5. Processing order fails:
   • opening invoice fails with:
     Module AcronisBackupService: Error occured [2]: filemtime(): stat failed
   • accepting order manually fails and activity log shows this error:
     Cannot get the email details. HTTP error code 404

Cause

Administrator's credentials are not saved in order processing.

Solution

Use one of these workarounds:

• In WHMCS administrator panel, navigate to Setup -> General Settings -> Ordering. Check Tick this box to generate random usernames for services rather than use the first 8 letters of the domain check-box. With this option enabled, a valid random username is generated. Please note that this option can affect other modules.
• Provide administrator's credentials manually before accepting the order.
