multiple issues after upgrade

first, a terrific module that has performed well for me...

the site is in development on localhost running Drupal 6.14.

after upgrading to 2.2 (and running /update.php), Web Links blocks were not presenting.

the link to a page promoted to front page no longer resolved to the node.

I uninstalled and then re-installed the module using hook_uninstall() and hook_install()

I then added a new link but encountered this error:
warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\drupal\modules\taxonomy\taxonomy.module on line 70. I saved the new link.

I Added the "All Links" block to an available region and it now appears and works properly.

When navigating to /weblinks, the new link appears, but the title link remains at the /weblink path and doesn't resolve to the node, which should be /content/new_link.

When navigating to taxonomy terms, e.g. /category/main-categories/fiiends/networking, links don't resolve to the nodes.

Finally, after removing this version and revert to 6.x-2.1, everything works as it should, with the module as well as other pathing issues.

This feels like some kind of taxonomy issue - thoughts?

highest regards for you Nancy...
