Your browser seems to block the execution of javascript.

However, this site relies on javascript and other modern web features.

Please consider the following:

  • Ensure that your browser is up-to-date.
  • Try to avoid using a deprecated browser (like Internet Explorer).
  • Find the javascript option in your browser settings and enable it.

When javascript is enabled, this page will automatically redirect to the root page of the C15 Reference. If the problem still persists, we recommend to try another browser.

In most modern browsers, the settings are available in the main browser menu - usually located on the top-right of the window.

Commonly, the settings can also be searched for specific keywords. Another common feature is to load the settings page or specific settings by typing directly into the address bar.

However, this all depends on the browser you are using:

Chrome/Chromium, Opera

Find the browser settings in the main menu and search for javascript. There should be an option for javascript in the Privacy and security/ Site Settings section, which should be set to "Allowed (recommended)".

(Alternatively, you can type chrome://settings/content/javascript in the address bar.)

Safari

Find the browser settings in the main menu under Preferences.... There should be a Security icon, opening the corresponding tab. In the Web content section, an option for javascript should be available. It should be set to enabled.

Firefox

Type about:config in the address bar, redirecting to the settings page. Search for javascript and find the javascript.enabled option. It should be set to enabled.

Edge

Open the settings page from the browser menu. You can search for javascript or find the option under Site permissions/ JavaScript. It should be set to "Allowed (recommended)".
