Can't level past 100

[Rhawk]

So I've been playing around with a fresh core of TrinityCore, but am struggling with a problem that I can't seem to solve.

I am struggling to have my characters level past 100. My worldserver.conf has max level set to 255, SQL xp_for_level table is updated to level 255, and I have altered my DBCEnums.h to the following:

enum LevelLimit : uint8
{
    // Client expected level limitation, like as used in DBC item max levels for "until max player level"
    // use as default max player level, must be fit max level for used client
    // also see MAX_LEVEL and STRONG_MAX_LEVEL define
    DEFAULT_MAX_LEVEL = 255,

    // client supported max level for player/pets/etc. Avoid overflow or client stability affected.
    // also see GT_MAX_LEVEL define
    MAX_LEVEL = 255,

    // Server side limitation. Base at used code requirements.
    // also see MAX_LEVEL and GT_MAX_LEVEL define
    STRONG_MAX_LEVEL = 255,
};

However, after all these changes, my characters are now not even able to level past 80. It makes no sense. Is there anyone who can maybe give me some guidance please?

Thank you
