Hi Nicole,
Thanks so much for reaching out with your BoldGrid Post and Page Builder questions.
So essentially the “Publish” and “Update” buttons are exactly the same thing. You will see the option to “Publish” the first time that you publish a new page and any edits after that would be considered “Updates”.
I think if you’re not seeing your changes you may have a caching issue preventing it from displaying correctly. Try clearing any cache associated with your website (including browser cache and any server-side caching agents you may be running.
A good way to test to see if your updates are being published correctly is to view the page in an incognito browser. If you can see the new changes there then you know that your older edits are just being cached into the page.
I hope this helps. Please let us know if there’s anything else that we can answer for you.
