\n\nIf you did not log out of the up.time UI before upgrading (refer to step 5 of Upgrading to up.time 7.2 of Later), you may see the following error after attempting to login after the upgrade:
Database is not responding...java.lang.NumberFormatException: nullat java.lang.Long.parseLong(Unknown Source)at java.lang.Long.valueOf(Unknown Source)at com.uptimesoftware.uptime.dataservice.simple.SimpleDataServiceQuery.getUserId(SimpleDataServiceQuery.java:22)at com.uptimesoftware.uptime.dataservice.query.GetLandingPageForUser.getUser(GetLandingPageForUser.java:97)at com.uptimesoftware.uptime.dataservice.query.GetLandingPageForUser.getLandingPageUrl(GetLandingPageForUser.java:53)at com.uptimesoftware.uptime.dataservice.query.GetLandingPageForUser.getResultSet(GetLandingPageForUser.java:28)at com.uptimesoftware.uptime.dataservice.QueryExecutor.getResultSet(QueryExecutor.java:14)at com.uptimesoftware.uptime.dataservice.ResultSetCommandExecutor.execute(ResultSetCommandExecutor.java:13)at com.uptimesoftware.uptime.dataservice.FrontEndCommandExecutor.execute(FrontEndCommandExecutor.java:11)at com.uptimesoftware.uptime.dataservice.FrontEndCommandType.execute(FrontEndCommandType.java:49)at com.uptimesoftware.uptime.dataservice.ProtocolHandler.run(ProtocolHandler.java:57)at java.lang.Thread.run(Unknown Source)
