when I do a manual cron I get this error:

Fatal error: require_once() [function.require]: Failed opening required 'sites/all/modules/sparkline/sparkline/sparkline/lib/Sparkline_Bar.php' (include_path='.:/usr/lib/php:/usr/local/lib/php:/home/ben61/public_html') in /home/ben61/public_html/newsblog/sites/all/modules/sparkline/sparkline/sparkline.module on line 231

I am also experiencing another error that may be linked to this as well:

There are no support clients configured/enabled.
