Once you’ve published content, you can still make changes to it and publish it again.
Log into Wagtail CMS.
Open the Pages navigation and select the content area you need at the top of the panel, for example jobs, publications etc.
You’ll see a list of all the published and unpublished content for that area.
Use the search input to find the title of your page.
You’ll see the relevant results.
Click on the page you want to edit and find the input fields you need to update by scrolling through the page.
Once your edits are made, you can publish the page via the green button at the bottom.
