fuseki webinterface does not show datasets - jena

Question

I have installed fuseki and start the server with
#!/bin/sh
cd /home/frank/localInstall/jena/apache-jena-fuseki-2.5.0
exec /home/frank/localInstall/jena/apache-jena-fuseki-2.5.0/fuseki-server -v --update --mem /testDB
The server is working and programs can store data in /testDB, but the webinterface does not show the datasets and I cannot add a dataset. When I try to query the interface says Please select a dataset.
I think I had this problem before and solved it by reinstalling the fuseki folder. I would like to understand what I did wrong and how to avoid this problem.
Thank you!

# Timeout - server-wide default: milliseconds.
# Format 1: "1000" -- 1 second timeout

# then 60s timeout for the rest of query.

# See javadoc for ARQ.queryTimeout for details.

How should I change it, if I want to datasets available to clients and to the webbrowser interface?

The problem was not with the config file, but with the default shiro.ini file in .../apache-jena-fuseki-2.5.0/run/shiro.ini. The default values do only allow local access and my access was a server. The instructions to change are clear enough. Here the relevant parts after the change:
[users]
# Implicitly adds "iniRealm = org.apache.shiro.realm.text.IniRealm"
admin=passXXX ## changed
[roles]
[urls]
## Control functions open to anyone
/$/status = anon
/$/ping = anon
## and the rest are restricted to localhost.
##/$/** = localhostFilter ## commented out
## If you want simple, basic authentication user/password
## on the operations,
## 1 - set a better password in [users] above.
## 2 - comment out the "/$/** = localhost" line and use:
"/$/** = authcBasic,user[admin]" ## enabled, removed ##
I assume that it is explained somewhere and I read it and forgot it when I moved from my localhost installation to a server. It would be helpful if the interface would indicate that permissions are not given in stead of inviting to select a dataset.
