Despite my misgivings about the whole process, due to a new security flaw I upgraded to WordPress 18.104.22.168 today. My links to individual entries stopped working at first, which nearly gave me a heart attack. But it seems to be ok now.
As much as I love using WordPress, deep down inside me somewhere I’m convinced that the whole site is balanced like a house of cards, and the slightest wind will topple it all.
Let me know if something doesn’t behave as expected.
