Once you have created a page in Drupal, it's easy to go back and edit it as follows:
- Log in to Drupal
- Type the address of the page you wish to edit into the address bar.
- Make sure that https:// is in the address bar (shown below)
If https:// doesn't appear (i.e. you see http:// or just www), type it in and reload the page.
- Click on the Edit tab that will appear on the page. (shown below)
- Edit the page as needed, clicking Save when you're done. (See the How do I create a page in Drupal? tutorial for more instruction on creating/editing pages.)
Your changes will take approximately 60 minutes to go live on the website once saved.
