Hi Cerstin,

In the GUI I could see, that the value of INDEX for "up-to-date" was "false".

this information simply indicates that not all index structures are updated yet. Whenever you activate UPDINDEX, your text and value will always be updated (i.e., "Text Index: " should always be followed by the flag "ON").

nothing happens. It looks like the script is waiting for some input -- the process does not stop.  The old BaseX server seems to be running somehow; I cannot start the server either.

maybe there's still a process running server-side? What output do you get when calling the SHOW SESSIONS command?
 
Best,
Christian
