With vBulletin releasing 4.2.1 yesterday we moved as fast as we could to get the newest skin updates out to you. If you upgrade you will see major style issue with the navigation which requires this update.
If you are looking to upgrade your current version we suggest you upgrade vBulletin to 4.2.1 and review the template changes most will have a checkbox stating template were done automatic. For skins with headerinclude updates please review the template history it’s a pretty easy update and finally the fun one, the navbar. You will want to install the new 4.2.1 as a backup skin and go within the additional.css and find the second instance of .navbar which will be within the navigation section and copy that entire navigation section and replace on your current skin. These are just basic instruction and will require some knowledge. We will not be posting anything more detailed but are here to help with any questions you have.
