Broken: Paged posts for month, day, category. Permalink problem?

Whee. This is now fixed. I found the answer in this thread.

Something was munged with my htaccess file. I basically scrapped and re-created it in order to fix the problem.

At the risk of multiple postings (this time multiple SOLUTIONS versus multiple questions), here are the steps I took to do so:

1. I copied all the contents of my .htaccess file (I have lots of custom redirects in there).
2. Deleted .htaccess file
3. Created new, blank text file named 1.htaccess on my local computer
4. uploaded via ftp to basie directory of my site (same place as where my index.php file is, one directory level higher than my /wp/ directory
5. Renamed file to .htaccess (removed 1), set permissions (chmod) to 666
6. In WordPress Control Panel, went to Options > Permalinks and pressed the Update Permalinnk Structure
7. Tested a “bad” page and IT WORKED!!!!!
8. Blessed WhollyHis (username of person in other thread who described solution)
9. Pasted all the static page redirects at the top of the page, before the # BEGIN WordPress line.
10. Tested again. It works. So I posted results here.
