It seems like your phpMyAdmin configuration storage is not fully configured, which might be causing some extended features to be deactivated. The configuration storage in phpMyAdmin is used for storing information about your databases, tables, and server settings.

To resolve this, you can follow these steps:

1. Log in to your phpMyAdmin dashboard.
2. Navigate to the “Operations” tab of any database.
3. Look for a section related to “Configuration storage.”
4. You should find an option to set up the configuration storage there.
5. Follow the prompts or instructions provided to complete the setup.

By setting up the configuration storage properly, you should be able to activate the extended features and ensure that phpMyAdmin functions correctly. If you encounter any specific errors or issues during this process, feel free to provide more details for further assistance.
