# Where to start when something is wrong

Troubleshooting and FAQ

Most problems have one of a handful of causes. Before you dig deeper, go through this routine - it solves or narrows down the majority of cases.

### The routine

1. **Read the System information warnings.** **System → System information** checks the store URL, primary currencies, weight and dimension, and payment methods. Fix anything that is not green.
2. **Read the log.** GrandNode logs through .NET logging - the console, `docker logs`, the IIS stdout log or Application Insights, depending on hosting. An exception message names the cause far more often than the symptom suggests. See [Maintenance tools and logs](https://grandnode.com/system-maintenance).
3. **Clear the cache.** Gear menu → **Clear memory cache**, especially after changing data outside the admin.
4. **Check the store scope.** On a multi-store installation, a setting saved for one store overrides the shared value for the whole settings group. Look at the setting with that store selected.
5. **Restart** (gear menu → **Restart application**) after installing plugins, editing `appsettings.json` or changing scheduled tasks.
6. **Reproduce in a private window**, to rule out the browser cache and your own customer session.

System → System information: the warnings at the bottom are the first thing to check.

### Reporting a problem

When you ask for help - in GitHub Discussions or from your support provider - include:

- the GrandNode version and git commit from System information, and the hosting (Docker, IIS, Linux);
- exact steps to reproduce and what you expected;
- the full error from the log, not a screenshot of the error page;
- which plugins and theme are active.
