Hello everyone, when a plugin doesnt work for me i usually dont make a big deal about it but this one would make a great addition to my site. However, when i install this plugin, it causes the right hand side bar to float left underneath the main blog roll. I have tried basic trouble shooting and everything but cant see to get it. I have left the error up and my website is below if anyone is able to suggest some things ??
