WordPress automatically saves as “AUTO DRAFT”

I’m a little unsure where exactly you can see the Auto Draft status? You write that it is set regardless of the title you enter. Can you show a screenshot of what you see? See: https://ww.wp.xz.cn/support/forum-user-guide/block-editor/#adding-screenshots

I’ve never had a problem with imgur and I’ve been using it for years. Just try again. You can also use any host that allows image uploads. Yes, you can even upload the image to your own WordPress and then post its URL here. Or you can use Dropbox, Google Drive… it’s entirely up to you. The important thing is that there is a URL that can be accessed.

You obviously have a lot of plugins and have also activated the commercial Divi theme. Something about this is interfering.

First, switch the theme to a standard theme such as TwentyTwentyFive and then try to create a page again. If the behavior has changed, it was due to Divi and you should contact their support: https://www.elegantthemes.com/contact/ – questions about commercial products cannot be answered here in the forum.

If it also happens with a standard theme, deactivate all the plugins you are using to rule them out as the cause. If the behavior is then correct, it was probably due to one of the plugins. Reactivate them one by one and test creating a new page each time until the problem reappears – then you have found the culprit plugin.
