Question: I am using alert plus web part but I got this error message on the screen: System.ArgumentException: Column Last_x0020_Run_x0020_Date does not belong to table Alert+ Configuration List. at System.Data.DataRow.GetDataColumn(String columnName) at System.Data.DataRow.get_Item(String columnName) at Bamboo.WebParts.VNCommon.a(String A_0, String A_1, Int32& A_2, Int32& A_3, Int32& A_4, Int32& A_5) at Bamboo.WebParts.AlertPlus.j()"
Answer: This error message is probably because the Alert+ Configuration List, in which the Alert Plus Web Part depends, has been changed and the column called Last Run Date has been removed. Please check your Alert+ Configuration List for this field. If it's not there, please add it.
