Could be one of the following…
1. A fatal JavaScript error in the theme or another plugin causing JavaScript to stop running.
2. A folder permissions issue on the server.
You would have to share a link to you directory for me to offer my exact advice.
3. The doc root of your server can not be found automatically.
To check if there is a JavaScript error, load the page in Chrome, hit the F12 key and then click the Console tab. All the page render errors will be listed here.
To eliminate a possible folder permissions error. Change the permissions of the following file and folder to 767:
../wp-content/plugins/connections/cache
../wp-content/plugins/connections/cache/index.html
If it is a doc root issue:
Add the following to the timthumb-config.php file found here:
../wp-content/plugins/connections/includes/libraries/timthumb/
This is what you need to add, make sure to change the doc root accordingly:
define ('LOCAL_FILE_BASE_DIRECTORY','/my/doc/root/');
What /my/doc/root will be, will depend entirely on the server setup. If you go to the the Connections : Dashboard admin page and look at the the System widget; there will be a constant named CN_PATH. The doc root should be the beginning portion of that path. What I can tell you is that from the wp-content on will NOT be part of the doc root. So that should help limit which part is the correct path.
Hope that helps.
