In Spark 2.6.3 - Can log in but cannot displayed

In Spark 2.6.3 I can log in but it can’t displayed so that i cannot see the online users… How do i resolved? Maybe the problem is in my computer or in Spark?.

I don’t fully understand you issue. You put username and password, press Login and Spark window doesn’t appear? No icon near the clock? You can try deleting Spark profile and start with a new one:


Or try the newest version ll4j/spark_2_7_0_668.exe
