Technical thing: for some reason, all of my CSS changes, which include a lot of formatting improvements and comment numbering, have stopped working
in both Firefox (3.x and 4) and Safari. They still work fine in Chrome. I haven’t checked IE. Updated: Cleared the cache in Chrome, and it’s gone there too. I haven’t changed my CSS, and I haven’t updated my browser, so I suspect it’s something on the WP side.
I’ve looked on the WordPress forums a little and put a support note in. I’m not, at this point, wildly impressed with WP for pulling this particular rug out from under me. This evaluation could be affected by the second “bad enough to be home from work” illness in two weeks. Makes me crabby.
I’ll post an update if I get one, but for the moment, please forgive the missing formatting and, in particular, the missing comment numbers.
Updated: Re-saving the CSS in the back end, then clearing my browser caches, appears to have solved the problem. I am still not wildly amused by WP doing whatever it was that caused the CSS to go away.)
