# Troubleshooting
Troubleshooting can be performed in multiple steps:
Check whether all modules are running properly. Multiple status pages are available here.
The Monitoring section explains how to reach them.
Check the log files. Errors begin with the prefix
ERROR
.The log files are stored in the /logs child folder of the ELO installation directory.
- You'll find the flows.log in the child directory of the corresponding Tomcat, e.g. /logs/ELO-ELOdemo-1.
- worker.log is stored in the corresponding Karaf worker directory, e.g. /logs/ELO-Flows-Worker-1.
With the complete error stack trace, you can check the cause for the error or share it with support, development, or the community.
