WordPress isn't reading the sticky_posts option

[rfischmann]

I've ran into this bug twice now. I try to set a post as sticky from WordPress' editor, but after saving nothing happens. It ignores the setting and reverts back to non-sticky.

However, I dug into MySQL and found out the post's ID is indeed set as sticky inside wp_options. So I'm not sure what's going on here.

Any way to debug this? First time I'm opening a bug report here.

Hi rfischmann,
This trac is for more or less confirmed bugs in WordPress core.
In your case, it's still too early to say exactly what went wrong. You need to do som troubleshooting first, and best place for that would be ​https://wordpress.org/support/forum/how-to-and-troubleshooting/

I'll mark this ticket as invalid. If, after troubleshooting, you find that there actually is a bug in WP core, then you can reopen it.

Good luck!

Pst! My guess would be that you first of all try with a default theme, like twentysixteen...
