A PHP replacement for bugzilla, focusing on separating code layers by using templates and a database abstraction layer. phpBugTracker is lightweight and easy to install, operate and administer. Most text can be customized for your application.
Great software, thank you.
Good project! But development stopped long time ago. I found fresh fork of that, converted to git at github. https://github.com/a-v-k/phpBugTracker
"magic_quotes_gpc is OFF! You must have magic_quotes_gpc set to On either in php.ini or in .htaccess (see http://php.net/magic_quotes for more info)." Never use PHP that requires magic quotes. It is an instant red flag that the developer doesn't know what they are doing.
