I have upgraded ato 1.12.5 version
Upgraded PHP is 7.0.29
I have application on shared hosting, so I have upgraded using Fantastico control panel. No Manual upgrade.
there is no error log for upgrade, so I don't see there is any break during upgrade.
Currently also agent/users working after upgrade.
If you can share any specific file to be checked, which has been changed to resolve this duplication. Please share, so I will check that code whether its there or not.
Thanks in Advance
