It looks like your site is running on a schedule that is deleting old privacy files when there are none.

The strange thing is that the PHP manual says opendir can return false. It also says for closedir

The stream must have previously been opened by opendir().

But it is coded with @. It seems like more recent versions of PHP changed how @ works, but surely everyone would be getting this error?

smileBeda · May 1, 2022, 2:30am

There are indeed changes to the @ at least in php
Also if some custom handler is set (which is theoretically possible to set server wide) it’d be thrown anyway, as I understand.

@darb are you ~~running php 8 or~~ perhaps setting an error handler?

I am running Ninja Firewall and CIDRAM to protect index.php; perhaps the source of the problem iif I am the only one effected?

joyously · May 1, 2022, 4:36pm

I doubt it is the problem.
I’m looking at a code formatting changeset from WP, where the @ was removed, but I can’t tell if that was when the closedir was moved inside the if statement, where it should have always been.
This error likely isn’t hurting your site, since it is a cron run, but it shouldn’t happen either.

It looks like there is a changeset upstream we should backport to fix up some potential PHP8 errors:
