the application is down, and my attempts to publish updates to my website are failing

Hello and good afternoon! I created a website using the platform and was very pleased with it, however that was when I was using the app and the app has not been working well for me across three different computers as of late. I wanted to make some additional updates but the online builder does not have the ability to publish the site, it seems. What can I do to fix this? it's the "crickety crotchety" website, connected to the domain, affirmationsforme.com.
