Sometimes things go wrong and Part-DB shows an error message. This page should help you to solve the problem.
## Error messages
When a common, easy fixable error occurs (like a non up-to-date database), Part-DB will show you some short instructions on how to fix the problem. If you have a problem that is not listed here, please open an issue on GitHub.
## General procedure
If you encounter an error, try the following steps:
* Clear cache of Part-DB with the console command:
```bash
php bin/console cache:clear
```
* Check if the database needs an update (and perform it when needed) with the console command:
```bash
php bin/console doctrine:migrations:migrate
```
