fixed by adding
#primary {
position: relative;
float: left;
width: 660px;
padding: 10px;
}
Thanks for your response. Now, if I want to make the first line of my post a bigger size than the rest or make one word bigger than the rest, do I maintain this in .css file or have to write html directly in the write post box?
Thanks harjeetsg
Your suggestion worked for me. The path was wp-content and I updated it to wp-content/uploads (although it says on the side that default is wp-content/uploads – I guess a mistake in 2.7) and it works when I use the browser uploader.
Thanks so much I was really struggling with this.
