I started by follow this article from MSDN about upgrading from 3.5 (or lower) to 4.0. I followed the manual upgrade process in the article since my site is kind of custom and also because i need to do the same changes in my production enviroment and wanted to know what is happening under the hood.

I should point out that i am running my code in IIS and not in the built in web server to mimic the production environment as close as possible.

• My first issue was that according to the guide on MSDN i should delete everything in the system.webserver section of my Web.Config. Previously in the article they had pointed out that if i had added any custom stuff anywhere i should keep that. Since i had a lot if custom stuff in my system.webserver section i did not do as the guide suggested here. I guess i should do a trial and error and remove stuff that i think is safe to remove. The reason why you should delete a lot of stuff in the Web.Config is explained by Scott Guthrie in his web.config blog post.
• After i followed the guide i tried to start my site and got the error “Unrecognized attribute ‘targetFramework’“. I got this error because i had to change the target framework on the App Pool. Just right click the app pool and choose “advanced settings” and you find this setting at the top. But i still got a “anonymous” 500 error after this.
• Then i tried to create a new site target with .net framework 4.0 and i got a slightly better error 500.19 that was actually “Googleable” and i found out that it was some kind of security issue. I moved my site to a folder outside my “my documents” space and .. another error! yey!
• I got the error ‘“PageHandlerFactory-Integrated” has a bad module “ManagedPipelineHandler” in its module list‘. This was also kind of easy to find and the post from Got Know How suggested me to reinstall .net framework 4.0 and finally everything worked!

It was actually kind of an easy upgrade. I should point out that i haven’t tested the site that much yet and it’s not installed in my production environment but it should probably not be that big of a deal.

The WCAT Fiddler Extension was exactly what i was looking for.

• It uses WCAT that is designed to test IIS.
• It use fiddler to record a test script.
• You don’t have to install Java, Python or any other framework.
• Everything is GUI based.

I really recommend you to check out this tool. You can read more about how it works on the Fiddler and the WCAT extension page.

Finally i realized that for some reason the “Attach to process” dialog had change the option “Attach to:” and it was set to “Managed (4.0) code”. When i changed it to “Managed (v2.0, v1.1, v1.0) code” it worked again.

I’ve actually never tried anything other than log based tools (AWStats, Analog, etc.), WordPress Stats and Google Analytics. So when I got to see a screenshot of Clicky the first time I was sold. But why try something new? Google Analytics is good!

• Google Analytics is pretty boring. Especially because they do not provide statistics in real time, therefore you cannot see directly how many visitors are on your site right now.
• The GUI is a bit too advanced. Eg I have many times tried to find “what times of day are the people on my site”. And the information is there somewhere but it is really hard to find. find.
• Google has a “monopoly” on this. Many complain that Microsoft has a monopoly but I must say that Googles monopoly is “more dangerous”. Take away Google Analytics makes the world’s information spread out a tiny bit more.
• If you build websites for customers it’s perhaps not entirely comfortable giving them a Google account to check their statistics. Clicky has a feature to White Label the product so that it looks like you made it yourself.
• Analytics has no good mobile interface. Of course, you must check the statistics when you are out and drinking beer with your friends. GA and the others doesn’t  even have real-time statistics so it wouldn’t been fun anyway.

Meet my new drug, Clicky!

Statistics are addictive, so if you feel that you have poor self-discipline you should stop reading now and do not check the following screenshots on Clicky.

call to undefined function mssql_connect()

When you Google this you mostly get the tip that you should put the file ntwdblib.dll in the /ext folder. I have a vague memory that this helped me the last time i had this problem but this time that didn’t help. I also noticed that MSSQL was not loaded when i run phpinfo().

Finally I found this post on the IIS forum that recommended me to run the command.

php-cgi.exe -v

When I did this I got an error message telling me that “This program cannot start because msvcr71dll is missing from your computer”. I then downloaded this dll file, put it in my C:\Windows\SysWOW64 (/system32 if you are on 32 bit). I also recycled my application on IIS and then everything worked. Hallelulja!

I have no idea if it’s related but i used “Web platform installer” to install PHP.

Windows Process Activation Service (WAS) is stopping because it encountered an error. The data field contains the error number.

The Windows Process Activation Service failed to generate an application pool config file for application pool ‘*’. The error type is ’0′. To resolve this issue, please ensure that the applicationhost.config file is correct and recommit the last configuration changes made. The data field contains the error number.

The Windows Process Activation Service service terminated with the following error:
Transaction support within the specified resource manager is not started or was shut down due to an error.

Not awesome errors. Of course i tried to Google for the problem and i found lots of other people with similar errors but most of them had to do with missing or corrupt config files and none of these fixes solved my problem. Then i tried to do a Windows Update and saw that i got an error there to. I googled and those errors and found this thread in one of MS forums. It was a fix for the Window Update error with the Code 80071A91.

How-to reset the File System Resource Manager if you receive error 0x80071A91

1. Click Start, click All Programs, click Accessories, right-click Command Prompt, and select Run as administrator.
2. In the Command Prompt window you will need to type the following, and press ENTER: fsutil resource setautoreset true C:\
3. Note: You will need to replace the C:\ with the drive letter that Windows Vista is installed on.
4. Restart your computer, and then attempt to install the failed update(s).

I did as described above and to my surprise the updates did work after this. And to my even greater surprise i entered the IIS Manager and (YEY!) the sites where up an running again and the Windows Process Activation Service where started and then i lived happily ever after.

$(document).ready(function () {
 $(".sub-menu").hide();
 $(".current_page_item .sub-menu, .current_page_parent .sub-menu").show();
 $(".sub-menu li").after("<li class='sub-menu-seperator'>|</li>");
});

This will hide all sub-menus, and then if a parent happens to have the class .current_page_item we show the sub-menu. My god i love jQuery.

Update:

As sushicodeur suggest you could of course do this only with CSS, it’s basically the same thing.

.sub-menu { display: none; }
.current_page_item .sub-menu, .current_page_parent .sub-menu { display: block; }

1. Issues with permissions for PHP and WordPress. Apparently with PHP you must give your IIS_IUSRS (What is the diffrence between IIS_IUSRS and IUSR btw?)  user permission to both your temp direct (upload_tmp_dir) and your regular upload directory in WordPress (\wp-content\uploads)
2. Remember to SAVE YOUR POST AS A DRAFT (or publish it of course) before uploading. I just spent the last ½ hour trying to upload images but all i got was “403 Access Denied”. When i saved the post everything worked perfectly.

Well .. this is the issues i found so far. Will update this post if i find anything else.
