We just recently upgraded our server to Moodle 2.8.6 and enabled the new backup format (we have three courses over 2GB) and we're getting an error backing up those courses. Our server is running on Windows Server 2008, PHP 5.5.26 and MySQL 5.6.25. Does anyone know what I can do to fix it? The error is below:
[26-Jun-2015 09:37:01 America/Denver] Default exception handler: Coding error detected, it must be fixed by a programmer: progress() value out of range Debug:
