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 reason you look at the default error logs (as indicated above) is because errors don't always get posted into the custom error log as defined in the virtual host. Assumes linux and not necessarily perl share|improve this

IIS 500 errors leave clues in the log Email ThisBlogThis!Share to TwitterShare to FacebookShare to Pinterest Yesterday I was playing around with thevalidateIntegratedModeConfiguration="true" setting on IIS 7.5. To my http://www.dotnetnoob.com/2012/03/iis-500-errors-leave-clues-in-log.html surprise I got an empty response back, with no indication of what went wrong. Looking at the response with Fiddler yields: HTTP/1.1 500 Internal Server Error Server: Microsoft-IIS/7.5 X-Powered-By: ASP.NET Date: Mon, 05 Mar 2012 15:59:52 GMT Content-Length: 0 There's not much to work with here! I checked the event log, there was nothing there. So I started looking around for an error log of some server error sort (I used to play with Apache back in the days) turns out there's no such thing in IIS. Some googling led me to an in-depth article:Troubleshoot IIS7 errors like a pro. I enabled detailed error messages for my website, still no luck. Finally, I figured out that the easiest way to get an indication of what's going on is to check the IIS log. In internal server error the default setup, IIS keeps the logs for each website in:C:\inetpub\logs\LogFiles. Here's a log entry from my logfile (shortened for readability): 2012-03-05 15:59:52 ::1 GET /Somesite/ - 443 - ::1 Mozilla/5.0 500 22 50 1 Notice the "500 22" in the log? That's the 500 error, along with its substatus. The substatus is the key here, as you can look that up inMicrosoft's document onThe HTTP status codes in IIS 7.0 and in IIS 7.5. Voila, my error was actually: 500.22 - An ASP.NET httpModules configuration does not apply in Managed Pipeline mode. I can work with that. Of course, you could also enable failed request tracing in IIS if you're a pro, here's a walkthrough by the IIS team:Troubleshooting Failed Requests Using Tracing in IIS 7. I tried it, and it also revealed the substatus of the response. Still, checking the IIS log was a much faster way of getting an indication of what the problem was, and sometimes that's all you need. So check your logs first, then start troubleshooting like a pro! Posted by André N. Klingsheim at Tuesday, March 06, 2012 Labels: ASP.NET, IIS 7.5, Ninja tricks, server 2008 4 comments: Anonymou
