One thing that could be wrong that there's another executable=... line in some of the other configuration files.There should be four (or five depending on how you count them, but anything in the others will override _default.cfg), so check that common.cfg has no executable (nor secrets-common or secrets-server, but all these should only contain comments. Oh btw. it would be good practice to put your password and other sensitive information in the *-secrets.cfg -files, but everything goes).
Once the server is up, check your process listing. The script should be there ... and indeed the log file.
