I was using [bd] API for a year or two, and recently thought I'd update it because of the new features. However, as soon as I upload the files, I get: An unexpected error occurred. Please try again later. The log says: PHP Fatal error: Class 'bdApi_Template_Helper_Core' not found in /forums/library/bdApi/Listener.php on line 64 Any thoughts? I'd like to reinstall.
