After choosing Interface > Default (not Classic) style, the “New” button at the very top of the screen still produces a new post in the block editor. That’s the button I’ve always used. I hardly even noticed the “Add Post” button. But with Default, that button does give me a choice of Block or Classic editor, and those two do deliver the different types of new post that one would expect. Apparently the Default choice is also responsible for restoring Classic Editor as an option when mousing over the title of an existing post in the list of posts. Not sure I understand the wording – Default vs. Classic – but it works.

I can't select the visual editor on WordPress, but only with "Desktop mode"

When an image is triggered on WordPress.com using Opera or Opera Mini it does not appear on the new screen, an image of broken link appears, working correctly in Samsung Internet Browser and Google Chrome, also in Firefox in older version.

WordPress provides four options: Media File, Attachment Page, Custom URL, None.

Using the option "None" the image will not appear in a new window, it is the only option that is 100% functional in Opera and Opera Mini.

The "Attachment Page" option opens a new window with the image but when viewing it in full size, a broken link image appears.

The other two alternatives did not work.

Why would I want a newer version?

well, i thinking here...

this topic here in windows section have a same problem to share videos to facebook.

My advice is the same... first report it has a bug to Opera Bug Report

And them try to use Opera Beta for mac, and say to us if in Opera Beta if has the same bug.
