I develop filer.
In settins.php
$settings->add(new admin_setting_configtext('filter_name/imgbaseurl',
new lang_string('imgbaseurl', 'filter_name'),
new lang_string('imgbaseurl_desc', 'filter_name'), '', PARAM_NOTAGS));I see the Settings page, can change the value, Filter is ON
but $CFG in filter() function does not contain this setting.
Why it can be?
Because you gave the setting name 'filter_name/imgbaseur'.
That means that it is not added to $CFG, which is loaded everywhere, which is good, it avoids bloat.
Instead, you need to load it where you need it, using
get_config('filter_name', 'imgbaseur');
Thank you very much!
It works.
But the documentation now is wrong.
I don't know whom I can ask to fix

It's a wiki. If you log in using your username and password from here, you can fix it yourself
