Hello,
I ran into the issue when `get_option` does not return any value:
`get_option( "_wp_session_{$this->session_id}", array() );`
It returns an empty value, but the value exists in DB and in cache.
I tested with 3 different methods one-by-one for option
`_wp_session_5c1f3b8058ca4b6cf9e637c31300bc23`:
==== 1) `get_option`
`get_option( "_wp_session_5c1f3b8058ca4b6cf9e637c31300bc23", array() );`
It returns an empty value (but sometimes it works fine)
==== 2) `wp_cache_get`
`wp_cache_get( "_wp_session_f5f8546504975ed39fb121b6b1b7c829", 'options'
);`
It returns correct value

`$wpdb->get_results('SELECT * FROM wp_options WHERE option_name =

It returns correct value

''I removed some private information here.''
----
So the problem only with function `get_option`. I checked this function as
well. It selects values for `notoptions`:
`$notoptions = wp_cache_get( 'notoptions', 'options' );`
And if current option exists in this array – it do return
{{{
if ( isset( $notoptions[ $option ] ) ) {
/**
* Filters the default value for an option.
*
* The dynamic portion of the hook name,
`$option`, refers to the option name.
*
* @since 3.4.0
* @since 4.4.0 The `$option` parameter was added.
* @since 4.7.0 The `$passed_default` parameter
was added to distinguish between a `false` value and the default parameter
value.
*
* @param mixed $default The default value to
return if the option does not exist
* in the database.
* @param string $option Option name.
* @param bool $passed_default Was
`get_option()` passed a default value?
*/
return apply_filters( "default_option_{$option}",
$default, $option, $passed_default );
}
}}}
Current option exists in this array, so it applies filter
"default_option_{$option}", function filter_default_option. But this
function check `get_registered_settings`, and there is no information
about this option, so it returns empty result.
That’s all information I have so far.
This problem exists at least for 1 year, for this time we always update
WordPress core and Plugins for latest version, and it does not any affect.

Hi and thanks for the report!
I updated the ticket description's formatting, which includes replacing
the “smart quotes” that came from the [https://wordpress.org/support/topic
/get_option-does-not-return-expected-value/ support topic].
