I have this same issue and on one site the sidebar goes away when i edit the index page along with a fine list of other features the team didn't test before releasing  this version

Joseph what theme are you running,  i am using macabre on my site. 

i have this problem too on macabre before update the themes. try to update your themes.

the only problem on macabre that i have now is newsfeed messup when scroll down after 8 times clicking view more and i didnt have this issue on other themes

thanks ben, yeah i wish they would add pagination to macabre 1 2 3 4 5 6 7 9....   clicking more each time is such a pain.. 

there is auto click view more plugins for newsfeed in store that i like it so much created by Mohammad

Dave, other guys, as Ben already noted, you need to update your themes. You have two options: 

1. update your themes manually: 

1. Besure that constant DEV_MODE is disabled in ow_includes/config.php file;
2. Download your current theme from our store;
3. Upload this theme to your site to ow_themes folder (overwrite existing theme);
4. After uploading was complete, enable DEV_MODE in ow_includes/config.php file;
5. Press F5 on any page of your site and disable DEV_MODE
   2 option: is to add these lines to your theme.xml file
   <developerKey>e547ebcf734341ec11911209d93a1054</developerKey>    <build>1</build>
   after this line:  <authorUrl>http://www.oxwall.org/foundation</authorUrl>;
   Then wait for 24 hours for the update to appear in your admin panel and update your theme

K thanks ross.. :)
