The Answer is NO sadly. They even warn you when you upgrade you can't restore it.

You can either re-direct your site to /forum if you add a .htaccess # This allows you to redirect your entire website to any other domain Redirect 301 / http://example.com/forums or if you want to add a index.php <META HTTP-EQUIV="refresh" CONTENT="0; URL=http://www.example.com/forum">

Create the folder forums, put your forum in there, change the config_global.php file

Yeah, its the wrong place edit the forums not permissions. See the bottom checkbox.

The easiest way (and if you're familiar with PHP) is to create custom blocks yourself. If in the plugin settings there is no way to choose which groups will appear in the list, then this is a problem with the plugin .. You can then use the standard IPB blocks. The Members block (System> Members), choose the groups that will appear, choose the Currently Online option and the Sort by Last Activity option. He will make a staff online, but will show with the delay of 5 minutes and will disappear when no one is online, as it should be.
