Redmine

Hey guys,
I recently had an issue with a bug caused by a custom version of an installed plugin (detailed here: ActionView::Template::Error (unidentified method 'identif...). However, since I still have not found a solution, is there any way for me to look at log files created by plugins? I understand that the base instance of redmine has log files, but is it separate from plugins? If it is, is there any way I can implement log tracking functionality into the plugin itself?
