There is a typo in ConversationManager.java in monitoring plugin
at line 93 - instead of table name "ofConParticipant" there is "ofConparticipant". On linux servers table names are case sensitive, this typo causes an exception
ERROR [ConversationManager] Table 'openfire.ofConparticipant' doesn't exist
com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: Table 'openfire.ofConparticipant' doesn't exist
at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:936)
at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:2985)
Please fix this in a new version of plugin. Thank you
