I'm afraid in this case need to manually clean and repair SSO. There are logs and command outputs required to understand what's happens with SSO. These outputs are not for shared forum.
You may ask for help Parallels Support.
MarkRe, try to turn on SSO and run
/usr/local/psa/admin/sbin/httpdmng --reconfigure-all
/usr/share/plesk-billing/integration --command=repair-all
/usr/share/plesk-billing/cache -c && /etc/init.d/sw-cp-server restart
Hi!
Can you explain your steps?
I tried to reproduce this bug on Debian6 i386 by following steps:
1. Install Plesk 11.0.9 (Standart)
2. Add Customer with Subscription
3. Add e-mail for Customer (Horde is set by default)
4. Upgrade to 11.5.29 -> All works fine
5. Add Billing, configure...
