looks like you tried to upgrade cart manually
To solve it try to:
1. Restore cart from backup (files + database)
2. disable caching in settings
3. clear error log
4. then try to upgrade via network admin menu-> extensions->install extension -> put installation key "abantecart_upgrade_120"
If some errors occurs post your error.log here
