Can also happen due to auto update/upgrade.
Uploading WP installation files should restore your website

Hmm… debug gives me this:

Maybe do as it says and follow the link.

You may have to reinstall WP.

Jaguar · February 23, 2022, 11:11am

deprecated does indeed terminate badly. line 3895 ends with " if ( e"

Can anyone tell me what is missing / point me to a working deprecated.php?

          	$_a = (int) $a->$_menu_item_sort_prop;
          	$_b = (int) $b->$_menu_item_sort_prop;

May be easier/safer to just reinstall though.

OK thanks for that. My file now matches yours, ending on 3905, but now the error has shifted to 3905, so deprecated.php must be corrupt somewhere. Is it possible to replace the entire file? Failing that it will have to be a reinstall I guess.

wackyblackie · February 23, 2022, 11:40am

You can download the entire file, but you may have to do some correcting of credentials, etc.

Open and click Ctrl+s and save it locally then use FileZilla to upload.

Absolutely! Or better yet, follow the guide that @KangJL already shared, which ensures that all files in your WordPress installation are correct, without any data loss:

Thanks for all the help guys
Trying to patch didn’t work, so I carried out a full reinstall successfully.
It turns out that WP introduced an update overnight, which failed, so that is the root cause of the problem. Updating to 5.9 failed also, and caused corruption previously, so now I need to understand why these updates are failing regularly.

KangJL · February 23, 2022, 1:23pm

Of course it will fail. You should upload the WP 5.9.1 installation files over your current installation. That should do the trick

Being unaware of the 5.9.1 update (until site was back up), I reinstalled from my saved 5.9 version. Once back up, I attempted the update from admin screen, but this also failed. I have now downloaded 5.9.1 and uploaded to site and all is now back at the new version.

My question is, why are manual ‘dashboard’ and auto updates routinely failing?

KangJL · February 23, 2022, 1:52pm

Due to limits of free hosting.

You can add this

define( 'WP_AUTO_UPDATE_CORE' , false );

to the wp-config.php file to disable WP update

Jaguar · February 23, 2022, 1:54pm

Ah-ha. No problem now I know what to expect
I will add that code as suggested. Many thanks.
