Sorry, but I am not sure what you are trying to do…
First, the account your provided does not have SP admin capabilities so we cannot look around the sp admin… a wp admin is NOT an sp admin… you add in the sp admin caps on forum – admins – manage admins…
second, where do you think the forum is installed?? you link in the nav menu points to: http://delreia.com/forum/open-forum/
but that is not valid or the location of the forum… its at: http://delreia.com/forum/
if you go the link in the nav menu, it will fail because the page does not exist…
If you go to the actual location that I mentioned, you will see a different message informing you that you have not created any groups or forums yet… so that is first step, create some groups and forums…
second, you will find you have some js conflicts on your site… It appears to be from your wp theme improperly loading jquery from off site instead of the version that comes with WP…
<script src=”https://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js” type=”text/javascript”>
and to boot, its a very old version of jquery so certainly conflicting with the version that wp loads itself…
