h3. Trouble shooting

h4. Q: My application crashes, and my apache error log shows no information.

There is a known problem with mod_fcgid: STDERR (including everything printed to std::cerr) is not
saved to the apache error log.

Wt uses STDERR by default for all error reporting. You can use a different log file in your wt_config.xml file ().

You may also consider using mod_fastcgi or the built-in web server (wthttpd) during development. The latter is especially convenient for development as it allows you to start from within a debugger, or diagnose memory-related problems with valgrind.
