My blog (www.imhappyfish.com/blog) got the date problem as well. I went into my theme editor, main index template, modified the font size for the date froma h2 to h4, it work well initailly, then I went back again to modified the spacing between the date and post title, after that the appearance started to get wrong even though I already taken off the spacing thing.
Can anyone tell me how to take off the image for the date as I did not see any image url in my theme template.
Thank you,
Joanne
