Once again I am out of my element, sorry. I have a D6.20 site that when I try to edit or add content of any type, except Page, I get this error:
Fatal error: Cannot redeclare filefield_widget_settings_form() (previously declared in /blah/blah/blah/blah/ipg.mellchandler/sites/all/modules/filefield/filefield_widget.inc:15) in /blah/blah/blah/blah/ipg.mellchandler/filefield_widget.inc on line 89.
This is a shared hosting site. I have contacted the tech support people there, but have not heard back from them yet. The told me I could view my error logs from a page provided by there control panel, but it was empty. Drupal's error log says, concerning trying to access those content type access, "access denied".
Would this mean I need to replace my "Filefield" module? The content types that have the problem are Product, Story, Photos, News Item (this type is a dynamic display block item).

My Bad
Once again the clue is in the error message. Somewhere along the way I some how copied part of the filefield module to the root and it was trying to call it from there. So the path was wrong. It was looking for:
/blah/blah/blah/blah/ipg.mellchandler/sites/all/modules/filefield/filefield_widget.inc:15)
but was finding this
blah/blah/blah/blah/ipg.mellchandler/filefield_widget.inc
When will I learn (as I bang my head on the floor 1,000 times). Dooohh!

Now I am looking like a bigger dult because i am repeating myself
Reinstall the module
This is a common error when you drop a new version of a module over an old one. Try deleting the module and placing a fresh copy in its place (after making a backup!) and of course running update.php if needed.
You can also check the system table, if you think there are path issues.
