I tried last night upgrading my blog to the Feb 12, 2005 version of WordPress. It failed.
Tried it this morning from work, and it is a success if you can read this.
I think it might of been my ftp client on my mac at home. I did all this installation work from the PC at work (bah to saturday fun!) as I’ve been waiting for production to give me material support I need. Short story, post to follow later.
I’ll be updating the wordpress files once a week hopefully, but let me know as quick as you can if you find any bugs or errors.
{edit} I’ve also turned off most of the plugins. The only one I still have active are Search Highlight (when you do a search, it highlights the word you are looking for), Stattraq for tracking website usage, and Kitten’s Spaminator for help with those pesky spam bots.
I’ve also turned off moderation on my blog for the next few hours, to see if 1.5 does a better job with spam
