Ended up being missing PHP modules (mysql, json, etc.) –user484474 Aug 7 '11 at 19:57 On ours, it was sending them to the access log (presumably because from Apache's point of view, it was working correctly and merely passing them along, from a deeper layer -- in our case, Passenger/Rails). Just putting this note here in case somebody is scratching their head. –Tom Hundt Jul 8 at 18:29 add a comment| 7 Answers 7 active oldest votes up vote 4 down vote accepted The error log usually has the (more) specific error. often it will be permissions denied or even an interpreter that can't be found. This means the fault almost always lies with your script. e.g you uploaded a perl script but didnt give it execute permissions? or perhaps it was corrupted in a linux environment if you write the script in windows and then upload it to the server without the line endings being converted you will get this error. in perl if you forget print "content-type: text/html\r\n\r\n"; you will get this error There are many reasons for it. so please first check your error log and then provide some more information. The default error log is often in /var/log/httpd/error_log or /var/log/apache2/error.log. The r

Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace. I replaced loglevel on apache config file: LogLevel debug After restarting, I'm getting the same error message without what could be called "a backtrace". As I understand there should be http://stackoverflow.com/questions/5641618/how-to-enable-loglevel-debug-on-apache2-server those 10 lines of redirects generated by mod_rewrite regex. After searching all over the internet I've found plenty of explanations of loglevel and mod_rewrite, but not a word of how to make loglevel debug work.

I won't bug you with the gory details here but just want internal server error to ask: Did anyone out there ever observe the web browser receiving a "http 500 inernal server error" while NOTHING alike appears in the apache's error and access log? It's currently not about the details here, but just that I believe this strange behavior should already lead into the right direction since I don't believe there are many possibilities where this can happen at all. When this internal server error happens, the PHP scripts continue running just fine without any failure, but of course the result they want to deliver to the browser will never appear, since the browser already thinks about his internal server error being the end of the world as he knows it.

That is, all of our in house applications log to specific directories other than the root Apache log; but if something happens outside the app (say the interpreter crashes), it would get recorded to /var/log/httpd/*. Could this be the case? &ndas

By default all you are usually going to see as evidence of this is a HTTP 500 "Internal Server Error" being displayed in the browser window and little else. The purpose of this document is to explain where to go look for more details on what caused the error, describe techniques one can use to have your WSGI application generate more useful debug information, as well as mechanisms that can be employed to interactively debug your application. Note that although this document is intended to deal with techniques which can be used when using mod_wsgi, many of the techniques are also directly transferable or adaptable to other web hosting mechanisms for WSGI applications. Apache Error Log Files¶ When using mod_wsgi, unless you or the web framework you are using takes specific action to catch exceptions and present the details in an alternate manner, the only place that details of uncaught exceptions will be recorded is in the Apache error log files. The Apache error log files are therefore your prime source of information when things go wrong. Do note though t
