Most Project Zomboid modifications can be installed automatically through Steam Workshop. Select the required modifications and install them.
If a modification is not loaded correctly:
- Open Steam Workshop (Installed) and click Info next to the affected modification.
- Note its Mod ID and Workshop ID.
- Open Configuration Files and locate servertest.ini.
- Click Text Editor.
- Locate the Workshop ID and Mod ID lines and verify that the values are correct. Remove accidental spaces or other invalid characters.
- If necessary, add the Mod ID and Workshop ID manually.
- Save the file.
- Start the server and check the log if the modification still does not load.
