Kibana shows blank sites in Discover, Management, ... after deleting/creation of default index pattern

Kibana isn't pointing to a trible node but I could fixed the problem. It seems to be that there was a problem with to many fields? I saved a part of the data from elastic, after that I was able to create the default pattern again. Finally I reindexed the saved data and it works. So, for now I'm not able to reprocedure the error/problem.
