Only nerds and the nerd-tolerant should proceed past this point.
I finally bought TextEdit because I was really annoyed with how slow the web interface for WordPress has been. Unfortunately, TextMate is not compatible with WordPress 2.2.2 or 2.2.3, for reasons that are quite incomprehensible to me. (They have to do with XMLRPC and the formatting of time and date stamps.) It seems possible that upgrading to WordPress 2.3 will make TextMate work again. Unfortunately, upgrading WordPress might break my theme or my plugins. It has been breaking RSS feeds, as well as crashing Safari.
I am a bit obsessive about proper maintenance of computer systems and it drives me crazy when things don’t work as they should. I find that I cannot really concentrate on anything else until the problem is resolved. As such, it seems likely that I will have a very poor night’s sleep before my trip to Montreal: whether because I spend too many hours trying to fix these bugs or because the distraction of their existence forbids me from getting any real rest.
The best option is probably to make a full backup of my WordPress 2.2.2 install (both on the FTP side and the MySQL side), try upgrading to WordPress 2.3, test my theme and plugins, verify that RSS works properly, and then see whether TextMate can be made to talk to the upgraded version. Of course, that would take hours, and now is really not the time.
[Update: 31 October 2007] This site has been upgraded to WordPress 2.3.1. Happily, this has resolved the issue described above. Please report any bugs, particularly relating to the spam filters.
