Magento 1.5.1 PHP Error After Installation
After installing the AddThis plugin for Magento today using the Magento Connection Manager's direct file upload feature, we see this PHP error in the error log:
PHP Fatal error: Class 'AddThis_SharingTool_Helper_Data' not found in /path/to/magento/app/Mage.php on line 520, referer: http://domainname.com/index.php/admin/system_account/index/key/3faf5acd9b45e8e5dd2d9fdae73e0584/
Is 1.5.1 supported? Is there a known fix for this issue?
Thanks, Scott
