I'm not sure where to start debugging this problem. I've added several mods and removed several that I could not get working. The result looks almost perfect from the viewers perspective, but I am left with ...
Category ID appears in the wrong field when I look at the delete category link; Check cat shows no errors, but when I click on show all I see all my links and not all my categories.
And I have a sub cat in 2x and can't seem to delete it even once. It shows up as not a category when I try to find it by name and won't delete with the delete category option.
I do have some backup files but I do not want to undo anything I may need.
Mods I think I have loaded are nested if, template-resources, category title mod, gramatically corrrect search results and total hits.
Thanks!

I also cannot create subcategories (not sure about new categories). Actually I can see the new sub cat in the categories list, but it doesn't show up with the link listings. So I cannot actually move any links into these new categories or they 'disappear'. Could the problem be with the build file and not a category file?

I think I'm getting somewhere, please help if you can.
I took backup copies of nph-build.cgi and category.cgi and this didn't help. Now I'm working with admin_html.pl and discovered even in another copy of links on another server with a clean install that the category check link points to links and not categories. I looked at my copy from the install download and sure enough the categories section of sub html_navigation { points the check link to links and not categories
<a href="$db_script_url?db=links&check_links=1">Check Cat.</a>

I changed this line to <a href="$db_script_url?db=category&check_links=1">Check Cat.

And now I am getting a category error report, but one that does not make sense.
Where should I be poking around or changing files?
