The GBC alerts you when certain functions of your GBC version might not work properly due
to limitations in your environment or configuration.
The degraded mode alert mechanism does not modify the internal behavior of the GBC but instead
provides visual alerts and explanatory messages to notify you of potential issues. Alerts can be
turned off by setting the theme variable theme-enable-degraded-mode-alerts to
false in the theme configuration file. For more information, go to Disabling degraded mode alerts.
Conditions that trigger degraded mode
Degraded mode is activated in the following cases:
Unavailable APIs: Certain APIs required by GBC, such as the Clipboard API, are missing in
the current environment. In most cases, this is due to the lack of secure context
(external link) (HTTPS or localhost required).
Non-secure context: The application is not running in a secure context (HTTPS or
localhost required).
Unsupported backend versions: The FGL or GAS versions being used are below the minimum
required versions. Check the Genero compatibility for the GBC page
for compatibility with your versions of FGL or GAS.
