I am getting this error when I run the cron.php for Magento. [24-Jan-2015 02:40:03 UTC] PHP Fatal error: Class 'Mage__Helper_Data' not found in /home/nli/catalog/app/Mage.php on line 516
I found a few other pages where someone else had this problem but I am unable to fix this. The two underscores must be the issue but I cannot find anywhere in my Magento directories with grep where there is any mention of Mage__Helper_Data or anything calling that class.
Please let me know if you have any ideas on what I could check. This has been happening for at least a couple months so I have no idea what happened or which plugins were installed at the exact time. Thank you!
