Problem with grid of posts

difficult to tell without seeing your site;

are you using Twenty Ten as your theme?

how many columns are you using in the template?
did you adapt the width of the columns for the number of columns?
(the styles in the article were just an example)

can you post a link to your site, pointing to a page with the problem?

Sorry I forgot to post the link

you have too many opening divs here at the beginning of the page template:

<div id="container">
			<div id="content" role="main">

		<div id="container">

			<div id="content">

remove this section:

<div id="container">
			<div id="content" role="main">

also, if you stay with 4 columns, you could change the width here;
example:
.col { float:left; width: 140px; ........
