## Knowledgebase
This section aims to provide some guidance on the most common issues that we see.
### Locating Log Files
The meta.log file can be found within the `logs` folder of your Plex Meta Manager config folder [right next to `config.yml`].
`meta.log` is the most recent run of Plex Meta Manager, `meta.log.1` is the previous run, `meta.log.2` is the run before that, so on and so forth.
### Basic Log File Troubleshooting
Wondering how to troubleshoot Plex Meta Manager and how to read through the meta.log?
**Using a text editor like [Visual Studio Code](https://code.visualstudio.com/) or [Sublime Text](https://www.sublimetext.com/) is recommended**
In all cases, the first step is to open the [`meta.log`](#locating-log-files) with your text editor and perform these steps:
1. Check that you are running the latest [`version`](#checking-plex-meta-manager-version) of your branch. Your current version can be found in the `meta.log` file either below the Plex Meta Manager ASCII art, or at the end of the run. If you are not on the latest version of your branch, you will see `Newest Version: X.X.X` below this. Ensure you [`upgrade`](../home/guides/local.md#i-want-to-update-to-the-latest-version-of-pmm) to the latest version of Plex Meta Manager.
2. When scanning your meta.log file, search for `[CRITICAL]` items first as these will definitely need to be fixed
3. Scan your meta.log file for `[ERROR]` and make a note of the content of the full line to start your search below on how to resolve
### Checking Plex Meta Manager Version
Checking the version: You will find that in your [`meta.log`](#locating-log-files) around the 8th-10th line and will look something like this:
```
| |
| Version: 1.17.1-develop10 |
|=================================|
```
If you are not on the latest version of your branch, you will see Newest Version: X.X.X below this. Ensure you upgrade to the latest version of Plex Meta Manager.
```
| |
| Version: 1.17.1-develop10 |
| Newest Version: 1.17.1-develop20 |
|=======================================|
```
