OK, well the important thing is it gets you up and running!
ShareThis – It’s possible that you might have some pretty aggressive popup ad-ware blocker of some type installed the could be interfering with it? Either way they are working and what you’re seeing is a local to you problem, so again good stuff.
As to the breadcrumb home going to the forum, yes you can do that. You do need to make a small change to a theme template so you’ll need to create a Child Theme if you haven’t already done so.
We have added child theme frameworks to the store for free, so all you’ll really need to do is download the relevant framework, add the template you want to change to the child themes folder (in this case reboot-child > templates > desktop > spHeadDesktop.php) and edit.
Find the function sp_BreadCrumbs() on line 146 and add the argument &homeLink=
The ampersand is important as it adds the new argument in succession, and nothing after the equals is important as it removes the home link meaning your breadcrumbs will start at ‘Forum’.
Hope that helps!
