wordpress 5.9.3 is breaking our website

What do you mean by “post cycle output widget”? Do you possibly mean the Gutenberg block Query Loop? https://www.ads-software.com/support/article/query-loop-block/

Can you post a link to the affected page? And also the HTML code of the Gutenberg block before and after? You can find the HTML code in the code editor, not in visual mode.

I mean this is how it was https://disk.yandex.ru/i/WPz8zt-JRZQYsw
and this is after the update https://disk.yandex.ru/i/G1664lPXGl_gYA

The layout now works as I’ve put the variable back, however, when $post_id is not there it breaks the layout, I’d like to sort this out so it doesn’t break anymore with the next wp update.

I am getting a similar issue when I go to edit any page. I get the “encountered an unknown error” box, with attempt to recover, ignore, copy text. My solution was just to reinstall 5.8 WP using the rollback core plugin. I run a business and I don’t have time to mess with a broken update involving people that apparently have forgotten how to code or are just lazy.

Many plugin publishers are listing compatibility for 5.8 along with 5.9, which tells me that this is a serious problem that apparently WP.org has no idea how to fix, nor probably cares.

Some people have said it is plugin issues, but I disabled all of my whopping 6 plugins, and that didn’t change what was happening. The error is in the core of the WP version, and considering it didn’t happen with the previous 50 updates to WP, I would imagine this is just a bunk release. I’d wait until they get a handle on what’s going on, because for all of my searching, I haven’t seen anything that correctly identifies the root issue yet, other than 5.9 doesn’t seem to like A LOT of things.

Upon a little more research, I found an older article prior to release of 5.9 that talks about the FSE – full site editing and having a theme that doesn’t support it. As the article mentions, I just tried it with the 2022 theme applied after backing up and 5.9 does indeed work as far as page editing goes, or at least no more errors.

But the 2022 theme doesn’t work with some of my plugins, and I would have to rearrange all the elements of my website, so that’s not gonna work, for me at least.

This seems very much like a “conform or die” update to 3rd party theme developers. Kind of sad that us WP users that just want to have a decent looking website and editing capabilities are caught in the crossfire of some weird digital pissing contest.

@tancredi: which theme do you use? Have you tried another theme?

@threadi I can’t “try” another theme as this is a custom one I must use.

Does anyone have some kind of solution to this issue?
I need to upgrade wordpress and I can’t do it right now because of this.

I would still advise to activate a default theme. Then you can narrow down the cause: if the default theme works, it’s your custom theme. Then something is possibly missing in this.

If you still see a problem in the WordPress core, I would recommend you to create a ticket at the core team: https://core.trac.www.ads-software.com
