# Markdown cache **(FREE)**
For performance reasons, GitLab caches the HTML version of Markdown text in fields such as:
- Comments.
- Issue descriptions.
- Merge request descriptions.
These cached versions can become outdated, such as when the `external_url` configuration option is changed. Links
in the cached text would still refer to the old URL.
## Invalidate the cache
Pre-requisite:
- You must be an administrator.
To avoid problems caused by cached HTML versions, invalidate the existing cache by increasing the `local_markdown_version`
setting in application settings [using the API](../api/settings.md#change-application-settings):
```shell
curl --request PUT --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/application/settings?local_markdown_version=<increased_number>"
```
