# Known issues

#### MySQL #1366 - Incorrect string value

This error happens when you try to insert characters that MySQL's current encoding doesn't support.

**Solution:** change MySQL's encoding to `utf8mb4`.\
1\. Open MySQL's `my.cnf`.\
2\. Add these configurations, save and restart MySQL:

```
[mysql]
default-character-set=utf8mb4
[mysqld]
character-set-server=utf8mb4
collation-server=utf8mb4_unicode_ci
```

#### KDR is not counted

Players report that their KDR is not changing.

**Solution:** deny the permission `simpleclans.other.kdr-exempt`. In some permission plugins, just add a `-` before the node. Others accept the `false` value.

#### Geyser | Error while opening GUI

Since SimpleClans is using player heads in its GUI, you may face with a [Geyser limitation](https://wiki.geysermc.org/geyser/current-limitations/).

After you try to open the menu (`/clan`), you may get the error in the console. \
In it you can find the mark of this error:

```
Caused by: java.lang.IllegalArgumentException: Name and ID cannot both be blank
```

**Solution**:\
Disable this option in your geyser configuration file.

```yaml
allow-custom-skulls: false
```
