There is no such thing as a downgrade. If you are having issues, restore your backup.

Brother ozzy i know backup would solve the issue .. i was just curious to know what thing raised that error ..

Cause even after disabling all hooks i was seeing those errors .. Lot more weird errors!!! all happened suddenly from past 3 months i didn't added new plugins nor any changes ..

And my host says me to remove DBSEO even after using the latest version

Maybe your server has changed php /sql version.

It's a template problem. It also seems like you might have changed something in the class_core.php file as line 4719 has no code on it by default, but the line before is a function call that looks like it extracts the template being rendered. What templates have you changed recently or have previously customized? One of those likely has something that 4.2.3 along with any new version of php your running is causing issues.
