http 500 error on IIS server

I was adding some php file uploader to my Microsoft server 2016. I had the software company dial into the server to help look at config and now all my sites are down and it only shows a http 500 error? And no matter what I change around I can't get the sites to give me any error messages or anything. I am unable to reach the software support people today for some reason and need to get the sites back up. Any clue on a way to troubleshoot this?

Main site is using .asp, and I added php which seemed to be working also. I just don't know if somehow the rights got changed? even the files with .html won't work either?

Any clue on a way to troubleshoot this?

try go to Event Viewer and see if there's some application errors recorded there?

also, try to change if there's any web.config, so to show the exact error on the page.

for example:

So what if its a rights issue? Normally I have a VPN connection into the server and just upload through a normal windows share the files instead of FTPing. So this morning I wasn't able to connect to my normal drive. So i reshared it and got it working. but wondering if the rights on the files would have changed or something.

I tried switching out to a more plain web.config as per the article you posted:

<configuration>
    <system.webServer>
        <httpErrors errorMode="Detailed" />
    </system.webServer>
    <system.web>
        <customErrors mode="Off" />
        <compilation debug="true" />
    </system.web>
</configuration>

Open in new window

Still only get 500 error no details

access log doesn't provide the error details, what about the event log at Event Viewer?

Your help has saved me hundreds of hours of internet surfing.

could the rights have gotten whacked. You know where do I need to allow for like the IUSR accounts? I'm not really seeing them and I know I need those somewhere. It should haven't changed but this issue is blowing my mind.

I think the error came from your ASP.NET application in which got a compilation error

Exception message: c:\webroot\hitekfab\dmxConnectLib\lib\zip\zip.aspx(9): error CS0246: The type or namespace name 'Ionic' could not be found (are you missing a using directive or an assembly reference?)

have you recompiled and copied all required dlls into the bin folder in your Web Application's folder in IIS ?

I wasn’t ever able to get the zip component to work. so I can uninstall that some how. but that was a while ago Smd hasn’t caused problem. but we are trying to install an upload module that would have files on the \bin folder. so maybe I need to dig in there?

Ryan Chong

yes, try see what libraries are available in the development machine's bin folder and replicate it to your web server

Shouldn't the IUSR and IIS_USERS accounts be added to the folder permissions?

ok, its down to user rights I believe. I have a testing site and I gave the user everyone full rights and the testing site started working.

So I added the IUSR account and gave read/read execute and that didn't work. I think before I had the IIS_IUSRS account added to, but when I try to add the group to the rights of the webfolder it can't find it? I can't remember how I did that before?

It is a user rights thing. I just don't understand. But I added IUSR and IIS_USERS back to the folder and bam. Back up and running. Dumb...

But thanks for the help!
