Not quite a millennium bug but with the roll over to a new year if there is no post for 2026 then the first main menu item shows as '25 – not 2026 (assuming you have a 4 digit first-year set).
Far from a major change and old installs will still work fine but I have adjusted to allow for this. You can download:
https://plugins.bludit.com/plugin/horiz ... chive-menu
and simply overwrite: php/hMenuBuild.php
There is also a minor tweak to plugin.php [field width]
happy New Year - ak
