500 Error on IIS

[faffoo]

It seems that the 3.0 RC does not work, at all on IIS. You are just recieving a 500 error when you upload the files to an IIS web server. It doesn't even work on localhost.

Is support for IIS in 3.0 being dropped?

[westi]

Is there any information in the error log?

Which version of IIS?

[faffoo]

No error log content. Iis version 7. Will not run any page in system. Just crashes with a 500 error. Is iis supported?

[nacin]

IIS is supported, in particular version 7. You may wish to try the support forums: ​http://wordpress.org/support. There are a large number of sites running WordPress on IIS -- including Microsoft -- and if it was other than an IIS configuration issue I imagine we'd hear about it quite quickly.

I'm not sure if it is part of this thicked.

I've updated my 2.9.2 WP under IIS to 3.0 RC1 and seems to work everything OK, but when i go to the Admin/Edit, the edit.php file never loads (blank screen)
It also happens with the upload.php file

Not sure why, But i do notice theres an IIS version of RC1 available at ​http://wordpress.org/wordpress-3.0-RC1-IIS.zip (From ​http://wordpress.org/download/release-archive/ )

Can you try enabling WP_DEBUG (Add define('WP_DEBUG', true); to your wp-config.php file and see if there is any error output then?

You may also need to configure PHP to log PHP Errors to file, I dont think IIS likes passing error messages through, and instead 500's. I dont have enough experience with IIS however to know the full details.

[faffoo]

The IIS version made no difference. It was a configuration option that I had been changing a few days ago was causing the problem.

I am now faced with another problem. The register link is not working. When you click register it takes you to wp-signup.php and returns a 400 error. Dont no why.

[dd32]

You may find the 400 errors will be fixed with [15081]

[faffoo]

Nope. That dosnt seem to fix the issue. This seems to be a fairly critical feature that is not working. I am getting a 404 error when i click the register link. The file is there though.

[dd32]

What type of 404 error is it? WordPress generated? or Server generated?

Is the request being passed to the filesystem, or are the Rewrite rules redirecting before it hits the file?

[faffoo]

The 404 is server generated. It is not a "nice looking" wordpress generated 404 error. For some reason the server is not recognizing the wp-signup.php file. Very odd. I cant tell wether it is filesystem or rewrite. How can I check? I removed the rewrite rules from web.config and it still didnt work.

[ruslany]

I cannot repro the 404 errors with the latest nightly build of WordPress on my IIS 7 server. When I click register it takes me to ​http://localhost/wordpress/wp-login.php?action=register and the registration of a new user is successful. How do you get to the wp-signup.php?

[faffoo]

Ok. That's weird, I have this set up with the network feature turned on and when I go to that URL it redirects to wp-signup.php and then gives a 404. Could you try the network feature and then see if it works on your server. I can't get this to work on my localhost and the entire package won't even install on my shared hosting account online. It just gives the original 500 error on every page. That is another page however.

[ruslany]

I see. I did not know about the network feature before. So I enabled the network feature and tried to register. It takes me to the wp-signup.php page. I can go through the registration process just fine.

I used the network feature that has separate sites as subfolders. I did not try the subdomain option though.

Can you enable detailed error messages in IIS and see if you get more information with the 404 error? You can contact me on ​http://ruslany.net/contact/ and I can try to help you to troubleshoot this.

See #13685 for a multisite, media related IIS rewrite bug.

[bloggus]

I'm using IIS6 and latest WordPress 3.0-RC2. Using isapi_rewrite for SEF links.

I can't see any of this issues at all.

[bloggus]

This is probably on IIS7 error, related especially to web.config.

[faffoo]

Higuys,

Thanks for all the help. It seems the 404 with the wp-signup has been fixes with the latest nightly build. Dont know what has changed but it worked. Great!

I still have my original problem however, when trying to install on a hosting package online, which is on IIS 7 aswell, I get a 500 error before I try and do anything. Not got a clue!

Best Regards

Lack of actionable feedback and steps to reproduce for what appears to be a server configuration issue. Moving to Unassigned.

[peaceablewhale]

@faffoo:

Did the IIS error page say anything? If so, would you posting the message here?

Since WordPress 3.0 has been released for sometime, I also suggest closing this as worksforme unless there is reporter-feedback.

[mrmist]

No feedback for a number of months, 3.0 in wide use now.

Re-open with feedback if necessary.
