Try giving the sidebar or page a shorter width/lengh
This is exactly the same problem I am having except in the opposite way – my sidebar is fine, it’s my content area that is at the bottom level of the sidebar.
I noticed that playing around with the float tags in the the CSS might fix it, although that only fixed part of my problem.
@idahoannie @kkradel after installing BP Template Pack plugin, you need to go through the process including imposing your active WP theme’s HTML structure onto the BP template files transferred into your WP theme’s folder in server.

If you require further assistance:
– open up your theme’s page.php file, select all and copy
– go to pastebin.com and paste the code, click on submit button
– copy the generated pastebin.com url and post here.
