To change open.mp server settings on FREAKHOSTING, open your server in the [Game Panel](https://games.freakhosting.com) and click **Game settings**. Change the fields you need, or click **Presets** to fill in several at once, then click **Review and save** and **Save changes**. The panel writes them to `config.json`, keeps the old file as `config.json.bak`, and the new settings apply after a restart. | Difficulty | Time | Works on | Panel page | | - | - | - | - | | Beginner | 5 minutes | Every FREAKHOSTING open.mp server | **Game settings** | ## What is on the Game settings page? **Game settings** is a form for your server's `config.json`. It has six sections. Click a section to open or close it. | Section | What it controls | | - | - | | **Server** | **Server name**, **Website**, **Language**, **Player slots** (from your plan), **Bot slots**, **Server password**, **Show in the server list**, **Allow queries** | | **Game mode and plugins** | **Game modes**, **Filterscripts**, **Plugins** | | **Game rules** | World time, weather, gravity, name tags, chat, stunt bonuses, weapons indoors, vehicle respawn time and more | | **Network** | **Player timeout**, **Allow 0.3.7 clients**, **LAN mode** | | **Remote console (RCON)** | **Enable RCON** and **RCON password** | | **Logging** | **Write a log**, **Log chat**, **Log deaths** | The toolbar at the top helps you find things: * **Search settings** finds a field by name. * **All** / **Changed** shows every field or only the ones you changed. * **Show advanced settings** adds 13 extra fields, such as streaming distance and sync rates. Leave them at their defaults unless you know you need them. ## How to change a setting **1. Open Game settings** Open your server and click **Game settings** under **GAME SETTINGS**. **2. Change the fields** Edit a field or flip a toggle. Changed fields get a `CHANGED` badge and a **Default** button that puts the default value back. The bar at the bottom counts your unsaved changes. **3. Fix any red values** If a value is out of range, a red message appears under the field and you can't save until you fix it. **4. Review and save** Click **Review and save**. The **Review your changes** dialog shows exactly what changes in `config.json`. Passwords are hidden. Click **Save changes**, or **Cancel** to go back. Click **Discard** on the bar to throw away all unsaved changes. **5. Restart** The panel shows "Restart the server to apply your changes". Click **Restart now**. The server keeps using the old settings until it restarts. ![open.mp Game settings Review your changes dialog showing the config.json diff with Cancel and Save changes buttons](https://mintcdn.com/freakhostingltd/m3ZOEtGPuZd9DW2_/images/games/open-mp/openmp-review-changes.png?fit=max\&auto=format\&n=m3ZOEtGPuZd9DW2_\&q=85\&s=f7fa0a8effafe88cba492ba1de549a8c) The Review your changes dialog before saving config.json ## How to use the Roleplay and Deathmatch presets A preset fills in several settings at once. Nothing is saved until you review and save. | Preset | What it sets | | - | - | | **Roleplay** | Local chat, name tags with line of sight, no stunt bonuses | | **Deathmatch** | Fast respawns, no stunt bonuses, no weapons restrictions indoors | Click **Presets**, choose one, check the changed fields, then click **Review and save**. Presets only change server settings. The way your game mode plays still depends on its script. ## Can I edit config.json directly? Yes. Click **config.json: open the raw file** at the bottom of **Game settings**, or open `config.json` in the [File Manager](https://help.freakhosting.com/portals/game-panel/how-to-use-the-file-manager.md). Stop the server first, keep valid JSON (quotes, commas and brackets), and save. For what each key does, see [config.json explained](https://help.freakhosting.com/games/open-mp/open-mp-config-json-explained.md). ## Frequently asked questions ### Why didn't my change work? Settings apply after a restart. Check that you clicked **Save changes** and then restarted the server. ### How do I undo a change? Before saving, click **Default** on the field or **Discard** on the bar. After saving, the previous file is kept as `config.json.bak` in **Files**; you can rename it back to `config.json` with the server stopped, or restore a [backup](https://help.freakhosting.com/portals/game-panel/how-to-create-and-restore-backups.md). ### Can I give my server more player slots? Your slots come from **Max Players** on **Startup** (your plan), written into `config.json` at every start, so changing **Player slots** here has no effect. For more slots, [open a ticket](https://freakhosting.com/clientarea/submitticket.php). ### Does LAN mode make my server private? It blocks everyone outside the server's own network, so players on the internet can't join. Use a **Server password** instead. See [set a password](https://help.freakhosting.com/games/open-mp/how-to-set-a-password-on-your-open-mp-server.md). ## Related guides > [card] [open.mp server guide](https://help.freakhosting.com/games/open-mp/open-mp-server-hosting-guide.md) > > Every open.mp page in one place. > [card] [config.json explained](https://help.freakhosting.com/games/open-mp/open-mp-config-json-explained.md) > > What each key does. > [card] [Set a password](https://help.freakhosting.com/games/open-mp/how-to-set-a-password-on-your-open-mp-server.md) > > Make your server private. > [card] [RCON and admin login](https://help.freakhosting.com/games/open-mp/open-mp-rcon-commands-and-admin-login.md) > > Turn on RCON and log in. > [card] [File Manager](https://help.freakhosting.com/portals/game-panel/how-to-use-the-file-manager.md) > > Edit and upload files. *** > [!NOTE] > > **Tested by the FREAKHOSTING team** on our Game Panel on 3 November 2026 (open.mp server 1.6.7.3218).
