<p>I have a problem on my linux mint. I installed OrientDB, create a database and successfully connect to this database with password and username root root. But after closing server.sh and reopening this server.sh i couldn't connect to this database, it write that Invalid password and username. Can u say what's problem? </p>

<p>I think that it's with permission, but i open console.sh as superuser, want to connect and write:
<em>CONNECT REMOTE:LOCALHOST/SAD ROOT ROOT</em>
write this error.</p>

Error: com.orientechnologies.orient.core.exception.OSerializationException: Cannot load database's configuration. The database seems to be corrupted.
