Apache2 500 error trouble shooting

.htaccessapache-2.2log-files

I recently updated some code on a staging server and now one link in the app throws an Internal Server Error…

There have been no changes to the .htaccess in doc root, but to remove this from the equation, I removed the .htaccess to test and no go.

Apache2 logLevel has been changed to debug and nothing is being logged. (watching tail -f /var/log/apache2/error.log and loading the page does not append anything to the log).

This code is running perfectly well on our development server. I know thats not much to go by.

Without the logs, I am stumped. Ths is a fairly complex app and without logs I simply cannot work out what the issue is.

Any help is much appreciated. Thanks in advance.

Ok guys, looks like it was just IE throwing the 500. Loading the page in Firefox shows a nice PHP parse error (the app is only supported in ie, so I had to switch my user agents to test).

For the record, I went through all my vhosts so make sure the logs were all correct, which they were, I'm still not sure why I was getting nothing logged.

Thanks for the help!

Apache2 – Avoid Logging Certain Missing Files in Error Log

I found a solution that works for me. I added these lines to .htaccess:

# Don't log missing files
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(artifacts\.jar|content\.xml|content\.jar)$ - [R=404,L]

It uses mod_rewrite. R=404 says to send 404 Not Found status code when client accesses any of mentioned files.

RewriteCode is there to make sure that file indeed doesn't exist. If I ever put one of those files into the directory, it will be served as usual.

This works great: mentioned files are no longer logged into error.log (that was my goal), but are still logged in access log (with 404 status).

Ubuntu – Why can’t I get Apache2 mod_dumpio working under Lucid Lynx Ubuntu

I've been struggling with this for a day, too. It seems they moved mod_dumpio output to the log level 'trace7' and disabled parameter DumpIOLogLevel.

I needed

LogLevel trace8

LogLevel info dumpio:trace8

for it to work.

Do remember that you usually have LogLevel at two levels, server level and virtual host level, check both.
