The core and DB versions dont match.
The core in our repository is not the same version as the 4.3.4 on TC repository.
But you are still using the database for the version on their repository.
Either find out what updates to run (remake DB with correct updates)
Or then you can just merge our repository with trinitycore's with
Code:
git remote add Trinty https://github.com/TrinityCore/TrinityCore.git
git pull Trinity 4.3.4
Resolve merge conflictions and you are ready.
This is likely the issue as I am viewing the stuff given so far. I am not exactly sure if I am correct.
