Devel Themer breaks admin menu

Good Day,

I am totally at whits end. I am also new to Drupal. And this week has truly been a learning experience. Now I had to copy a development Drupal from a production website.

I upgraded from Drupal 6.7 to 6.9.
I backup and restored the mySQL 5.1.3 database.
I am using PHP 5.x.
I am using IIS 5+

I am experiencing the exact same symptoms. The menu won't show up on the newly released 6.9. No content can be accessed from menus or links (404 instead), unless "?q=" is manually inserted into URL. Clean URL reports that Clean URLs are enabled. In addition, none of my images are showing up and my javascript is not working. All of this was working on the production server and before the upgrade.

I have looked at the .htaccess file and I have read that the file has not changed.
I even went to the systems table and set the status to 0 and back to 1 for the modules.

At this point, I have no idea what else to do. Can you help me.

Thanks.
Deetra

@ #4: same here

I cannot replicate this issue - do you have the Devel Themer module enabled? Do you still experience this issue after disabling Devel Themer? If you are, did you clear your site's cache?

When the Theme Developer module is enabled, the flyout menus cease working. Based on interaction with tha_sun on IRC, I implemented his recommended fix, which seems to work nicely.

Two changes were introduced where:

$output .= theme('admin_menu_item', $link, $data['link']['has_children'], admin_menu_tree_output($data['below']), $data['link']['in_active_trail'], $extra_class);

was converted to

$output .= theme_admin_menu_item($link, $data['link']['has_children'], admin_menu_tree_output($data['below']), $data['link']['in_active_trail'], $extra_class);

and

$output .= theme('admin_menu_item', $link, $data['link']['has_children'], '', $data['link']['in_active_trail'], $extra_class);

was converted to

$output .= theme_admin_menu_item($link, $data['link']['has_children'], '', $data['link']['in_active_trail'], $extra_class);

Better title.

Committed this patch and also removed the corresponding hunk from admin_menu_theme().
