This can be caused if there is a fatal error in the script. From PHP Runtime Configuration: Although display_errors may be set at runtime (with ini_set()), it won't have any affect if the script has fatal errors. This is because the desired runtime action does not get executed. You should set display_errors = 1 in your php.ini file and restart the server. share|improve this answer edited May 6 '15 at 3:35 answered Mar 4 '14 at 11:40 Philippe Signoret 3,37211333 And I will see errors in the browser console, right ?

Check out this link for http://stackoverflow.com/questions/22170864/500-internal-server-error-how-to-debug a brief description of what a 500 error mean, http://www.checkupdown.com/status/E500.html. Below is a sample of what a 500 error may look like in your browser. Step 1 In order to access your debug log you will need to first turn on the debugging and then access the debug log. If you don’t already have access to your site via SFTP, log into your my.pressable.com accout, there your will find a tab named “Users/FTP” Once you are on that page, you will see something similar https://kb.pressable.com/troubleshooting/debug-500-error/ to what you see below. Note the information you will need is as follows: the URL, Port, Username, and Password (to get password, click on the Reset Password). This information will be needed if to access your site via SFTP. If order to acess your site via SFTP you will need an FTP client, we recommend using Filezilla, this is on both windows and OS X, you can find it here https://filezilla-project.org/.

This will download the file. After that it should open the wp-config file in your defualt text editor. You will need scroll down and find the section that is pictured below. By default your debug log will be set to false. You will need to change that text to “true”. Be sure to NOT edit anything else in that document as it can render your site unusable. Once you have saved the file, upload it to the same directory by just dragging that file in the directory to overwrite

However; there is nothing showing up in the Application Event Log where I would expect to see a (more) internal server error detailed description of the entry. How can I go about diagnosing this issue? iis-7.5 windows-event-log 500-error asp.net-mvc share|improve this question edited Jul 16 '12 at 7:55 asked Jul 15 '12 at 21:25 Greg B 4843825 I've had the exact same issue here. In my experience, if the event log is empty than the request wasn't correctly routed to the worker process. In one of our recent deployments we saw the app work intermittently with about 50% of the requests randomly failing with the 500 error and nothing in the logs. I suspect something is going wrong with the AppDomain unload that occurs after deployment. Out of curiosity, are you running antivirus in your production environment? Does an IIS reset solve the issue (until the next deployment)? –ShadowChaser Feb 21 '13 at 16:17 add a comment| 4 Answers 4 active oldest votes up vote 22 down vote accepted Take a look at IIS7's Failed Request Tracing feature: Troubleshooting Failed Requests Using Tracing in IIS 7 Troubleshoot with Failed Request Tracing The other thing I would do is tweak your
