Controller doesn't start anymore - org.apache.tomcat.util.digester.Digester fatalError - Parse Fatal Error at line 1 column 1

Hello,

My openremote installation (Rasp PI 3 - OR controller 2.6 - ZStick ) was working fine and suddenly, stopped.
the problem seems to be at the Tomcat/ apach level which does not start anymore.

Starting OR manually ( ./openremote.sh run), i get the following error message :

Looking at some forum, I have seen that the problems can come from the file server.xml corrupted.
I have a reloaded all the files in openremote/conf folder from the oringinal archive, but I still get the same error. :-(


Can someone please help me ?

Thanks a lot for your help and your time,

Regards
Jerome

Hello,
After some tests I have found that is was the file

/openremote/security/users.xml

which was corrupted.
For some unknown reason, this file was empty instead of havinf the few following lines :

<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
</tomcat-users>


So, I have reloaded the file file with the original one and it works fine now :-)
