When clicking on Participation and Grading for Wikis, the following error will appear:
blackboard.persist.PersistenceException: javax.servlet.ServletException: java.lang.NoSuchMethodError: blackboard.plugin.grading.api.tag.ViewContributorsTag.setShowEmptyUrl(Ljava/lang/String;)V
For reference, the Error ID is 3127abf5-f672-432f-8dd1-bcfe130963d6.
This is a known issue. The proposed fix from Blackboard Support will be applied at an available low-usage opportunity, possibly during the March mid-semester/mid-term break.
Please plan accordingly as the Wiki tool is not fully functional at this time.
