I run a blog at http://www.ipnewsblog.com. I recently (within the last week) upgraded to 220.127.116.11 (from 1.5), and all seems to be going well. A few users initially complained that they could not post -- and I informed them that they should flush their cache/cookies and everything turned out fine.
However, one user swears up and down that she's done all this, but still gets no love. She can log in, go to the write page, type up an article, and when she hits submit, everything just dissappears. It doesn't save, and all her work is lost. She's told me that she's tried to flush her cookies/cache, but there is no love. She's using a windows XP (Pro) box, and running IE (I believe, at least 5.5). Its hard for me to give any other diagnostics, due to the fact that she's a remote blogger.
The bloggers using firefox have no problems (shocker). She's a bit tied to her browser, so I'd like to give her a better answer than a snarky, 'Go use Firefox.'
