unsupported D6.8?

I'm using drupal 6.9, i setted it for admin themes and I got this error in any page, apart in user page:
Fatal error: Call to undefined function phptemplate_menu_item() in /home1/fornitur/public_html/sites/all/modules/dhtml_menu/dhtml_menu.module on line 115

Confirmed. I see the following error in the administration section for themes: "This version is incompatible with the 6.9 version of Drupal core."

Ubuntu 8.04
Apache2.2
PHP 5.2
Drupal 6.9

This issue is being closed because it is against a branch for a version of Drupal that is no longer supported.
If you feel that this issue is still valid, feel free to re-open and update it (and any possible patch) to work with the 7.x-4.x branch.
Thank you.
