comment error message: white text on yellow background

When posting a comment at asksage.sagemath.org, I got an error message which was tough to read since it was white text on a yellow background. I've mentioned this before at asksage, and I think Evgeny may have addressed it already, but it happened again today and that reminded me I had wanted to mention it here too. Edit: The link is [here](http://ask.sagemath.org/question/89/setting-precision-in-sage#217) (my comment "I'm afraid the best I could try is . . ." to my own answer). I'm afraid I don't remember the particular error message, but I did have the impression it was a server problem; the trac.sagemath.org site was having serious problems for a few hours this morning, so it may not necessarily be a bug with askbot. I mostly just wanted to comment on the readibility of the error message :)
