Disabling PHP Output Buffering
By default on most PHP configurations, the "output buffering" setting has not been enabled, and therefore doesn't cause an issue. However, if it has been enabled on your server, in order for Jamroom to function properly, this output buffering must be disabled. With output buffering enabled, you will have problems streaming media from your server, and some items may appear to not load fully.
To disable ouput buffering for Jamroom, add the following line to your jamroom/.htaccess file:
php_value output_buffering Off
Save the .htaccess file, and you should be all set. If you continue to have issues, you may need to contact your hosting provider and have them disable this setting at the server level.
