I have made changes to my stylesheet. These changes do NOT appear when I look at the blog using Firefox 14.0.1 on my Luinux Ubuntu 12.04 machine. Yes, I've cleared the cache. I even tried looking at it on a different computer which had never gone to the site, and the old version (pre-stylesheet changes) still displays. I also tried using IE on a Windows 7 machine and only the old version displayed. However, when I view the page on my cell phone using the Opera Mini browser. it displays the page using the updated stylesheet. Why would Firefox and IE not display using the current stylesheet when Opera Mini does?
