I installed the JIRA Suite Utilities plug-in. I modified one of my workflows to add a post function. Now users are getting this error when trying to transition/move a status in that workflow. "Could not load FunctionProvider class. It seems that you have tried to perform an illegal workflow operation. If you think this message is wrong, please contact your JIRA administrators."
I am also getting this error "Error rendering 'com.googlecode.jira-suite-utilities:transitions-summary-tabpanel'. Please contact your JIRA administrators." in other workflow/projects that are not using the plug in.
