I went back to the 4.01 download and pulled out everything I did not need or did not want to upload/overwrite:
- darkblue-borders (already edited)
- zipData1.sql (to save time)
Then I reuploaded the remainder (678 files) overwriting what was there, just to be sure I had not overlooked something the first time. It does not seem to have changed anything, still can't sort.
On the cookies, I've deleted them on this computer many times (Windows 7/IE8) and did again tonight but it didn't help, but this computer has some quirks. However, I can't get the classifieds to sort on the computer at the public library either (Windows XP).
