Means you do something like:

pawn Code:

MyFunction()
{
    if(somevalue)
    {
        return 1;
    }
    new string[64] = "a text";
    return string;
}

In one function, all return types must be consistent (that's what the error says). So you need to return all arrays (strings), all integers or all floats, but not a combination of them.
