Unable to delete folder(s) from uploads using File Direct API

The change in line 567 is just to check if the file is readable. If the file isn’t readable, then it should not be readable.

What is your hosting configuration?

Edit: Nevermind, I see the issue. I’ll bring it up to the maintainers. In the meantime, if you remove the is_readable() check, it’ll work again.

It appears this was actually fixed, so we need more information. What type of hosting are you using? Windows or Linux? Basically, what is the circumstances that cause this is_readable check to fail?

@otto42, thanks for looking into it.

So we have our inhouse WP plugin framework in which we developed file transients to get rid of some hard caching issues. So we save certain info in our file transients and remove it every time admin make changes in the system.

While this happens to so many of our clients as well as in our local setups.
Here is my own local setup where this issue occurs.
