Littlebit - From looking at your site, I don't see anything else that doesn't seem to be working properly. However, there were a few templates that were changed from 2.0 to 3.0, so I'm going to attach the readme file from that version which includes a list of all templates that were changed, and how they were changed. You may want to look over that to be sure you won't have any problems in the future. Also, any of your templates that have not been customized will not need to have anything changed as the upgrade file should have overwritten any original templates. Oh, it's also possible that you would have a couple of extra options in the Admin CP (such as News Smilies) since those would not have been removed with the way you upgraded. It really shouldn't affect anything, but if you would like to just highlight all your myvbindex options and paste them here, I can look over them and tell you how to easily get rid of any that aren't used any more. Again, it won't affect the way the script functions, but may help to prevent some confusion later.
mcyates - It looks like you missed a step in the install file. For the images to work properly, you have to change the path to your images for each style. Here are the instructions from the install file:
Next find the Styles section near the bottom left frame in your Admin CP. Click on "Modify" under Styles, then click on the [fonts/colors/etc] link. Near the bottom of this page you will see a section for Image Paths. Set the "Image folder path" and the "Title image path" to the full URL for your images folder inside your forums (ex - /forum/images or
http://yoursite.com/forum/images). You must do this for each of your styles, otherwise your images will not show up.
