If your vendors aren't working in 2.3.0, simply save or execute this coding into your database. Its not a complex problem, but the npc flags were changed around and this fixes em. Hope this helps some of yall out there. Here are the stats of what our server is currently running:
-=CoreWoW Server=-
Core: Ascent 2.3 TRUNK r2340
Database: NCDB 0.2.2 with the latest sql table and localization updates
