Fast answers to the installation, economy, configuration and migration issues seen most often.
The plugin does not start
Read the server console first. Confirm Vault and a compatible economy are active, fix the reported dependency, then fully restart the server.
SQLite or MySQL?
Use SQLite for a straightforward single-server setup. MySQL requires Pro and is intended for networks sharing one auction house.
Why are network balances inconsistent?
ModernHDV synchronizes auction data, not economy balances. Your Vault-compatible economy must be shared or synchronized across the network separately.
Can Free be customized?
Yes. Free exposes GUI, category and language customization through YAML. Pro adds in-game administration and faster reload workflows.
Can Pro migrate Free?
Version 1.2.0 includes automatic migration for the main files and storage transfer between SQLite and MySQL. Back up and never run Free and Pro together.
