If you are having trouble with your Apache server software, you should
take the following steps:
Check the errorlog!
Apache tries to be helpful when it encounters a problem. In many
cases, it will provide some details by writing one or messages to the
server error log. Sometimes this is enough for you to diagnose & fix
the problem yourself (such as file permissions or the like). The default
location of the error log is
/usr/local/apache2/logs/error_log, but see the ErrorLog directive in your config files for the
location on your server.
The latest version of the Apache Frequently-Asked Questions list can
always be found at the main Apache web site.
Check the Apache bug database
Most problems that get reported to The Apache Group are recorded in
the bug database.
Please check the existing reports, open
and closed, before adding one. If you find that your
issue has already been reported, please don't add a "me, too"
report. If the original report isn't closed yet, we suggest that you
check it periodically. You might also consider contacting the original
submitter, because there may be an email exchange going on about the
issue that isn't getting recorded in the database.
