Why can't I send or receive messages on WhatsApp?

Possible Instruction:

If you are unable to send or receive messages on WhatsApp, try the following troubleshooting steps:

1. Check your internet connection. WhatsApp requires an active internet connection to send and receive messages.

2. Restart your phone. Sometimes a simple restart can solve the issue.

3. Check for WhatsApp updates. Make sure you are running the latest version of WhatsApp.

4. Clear the cache and data of the WhatsApp app. Go to your phone's settings, then "Apps" or "App Management", find WhatsApp, and select "Clear Cache" and "Clear Data".

5. Check if your phone's date and time are accurate. Incorrect date and time settings can cause issues with WhatsApp.

6. Check your phone's storage. If your phone's storage is full, WhatsApp may not work properly.
