With the new semester approaching and due to the recent pandemic, several schools urgently added the synchronous classroom module. However, when the synchronous classroom recording playback plugin was launched, some teachers reported that they couldn’t see the video.

- This feature allows Moodle to load all plugins' JavaScript files individually (without combining/packing, which normally speeds up downloads), making it easier for us to test.
- Another setting is to disable JavaScript caching and minification. Like the previous one, this allows you to see the original code in the browser, making debugging easier.
These two common settings can be found at: Site Administration ► Appearance ► AJAX and JavaScript, as shown in the figure.
