I am trying to edit some code I have on pages, however, the source code button is no longer visible on any page to edit snippets I have added previously.

I am completely stuck without this option and have no idea why it has gone. On another website I have created using pages the option button to edit code button is still there to switch from WYSIWYG.

 

Thanks for any advice.

Have you checked your group permissions to confirm that "can post html?" is still set to yes? 

You need to add the button to your Editor.

Go to ACP > customization > Editor.  You can add or remove any buttons.
