Unknown server tag ‘asp:ListView’ – Windows Server 2008

We recently upgraded a server to Windows Server 2008, and some of our old applications decided that they no longer want to work. We are now having problems with the asp:ListView object, constantly getting the error Unknown server tag ‘asp:ListView’.

I’ve found a few articles (quite a few) that all point to the web.config file, saying that you need to add these lines:

  <add assembly="System.Web.Extensions, Version=, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>

    <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
    <add tagPrefix="asp" namespace="System.Web.UI.WebControls" assembly="System.Web.Extensions, Version=, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>

The best (and only) solution for the problem Unknown server tag ‘asp:ListView’ on Windows Server 2008 is to completely uninstal the .NET Framework 3.5 and the .NET Framework 3.5 SP1. Download them from Microsoft – Do not install them through the Server Roles feature in Windows Server 2008 – and reinstall them from the installation packages.

Hope this helps!

iTunes 8 Will Not Load or Install on Windows Vista – You must restart your system for the configuration changes made to iTunes to take effect

Recently, I updated my office computer to iTunes 8, and since the update, iTunes just will not load for me. Once I updated iTunes and restarted my system, I get the following messages.

First Message

Please wait while Windows configures iTunes.

Second (most frustrating) Message

You must restart your system for the configuration changes made to iTunes to take effect. Click Yes to restart now or No if you plan to manually restart later.

Basically, my iTunes installation is in a never-ending loop of configuring itself and then asking for my computer to be restarted. Is there any way to get around this problem? I’ve tried uninstalling iTunes and deleting all of the files associated with it, but once I downloaded and installed iTunes again, I encountered the same problem. Endless loop.

Windows Vista is Extremely Slow to Recover from Sleep/Hibernation Mode

I recently installed Windows Vista Ultimate on my home PC, which previously had Windows Vista Home Premium installed. Upon installing Windows Vista Ultimate, I have had a problem of the PC taking a terribly long time to wake up from sleep mode. It literally takes 5-7 minutes. When I’m done using the computer, I’ll press the “SLEEP” button on my keyboard, which will put the computer right to sleep/power saving mode. Upon returning to the computer, I can press a mouse button or any button on the keyboard to wake the computer up. When it wakes up, I am almost immediately presented with the logon/password screen, and after entering my password, the desktop will display, but is unusable for about 5-7 minutes. When I was running Windows Vista Home Premium, the desktop would be immediately useable with no lag time at all.

Has anyone else encountered this problem? Any solutions or workarounds? Probably should just keep using my Mac, right?

Genius results can’t be updated right now. An unknown error occured (-50). – iTunes Genius Error

Since the switch to iTunes 8, everything (for the most part) has been running smoothly. I’ve been able to create some great playlists using Genius, and I’ve also found some songs that I really like. But then, out of nowhere, I get the following error:

Genius results can’t be updated right now. An unknown error occured (-50).

Please try again later.

Is this just an intermitent problem, possibly caused by a bad network connection, or a problem with Apple servers? Has anyone else encountered this problem?

iPhone Problems – No Sound When Typing, No Key Click Sounds for Keyboard

My iPhone is running firmware version 2.0.1 and some of the time, the keyboard does not make the clicking sounds. It is very random as to when this happens, sometimes I can just switch the phone to silent mode, then back to normal and that will solve the problem, but sometimes I need to power the phone off, and then back on.

I have yet to install firmware version 2.0.2, has anyone else encountered this problem? If you have, does the new firmware version fix it?

No Listings in Microsoft Outlook Address Book – Problem Solved

I don’t know why this happens, but from time to time, when I open Microsoft Outlook and try to type a message, I click on the “To” or “Cc” button within the compose message form, and my address book either gives me an error, or comes up entirely empty. Well, I think I’ve found a simple solution for all of you who have this same problem.

I use my Outlook Contacts as my address book, so if you use a Microsoft Exchange Server or anything like that, this may not work for you. Okay, so here’s the trick:

  1. Click on your contacts tab from within Microsoft Outlook.
  2. Click File > Folder > Properties for “Contacts”.
  3. On the General tab, check the box toward the bottom that reads: “Automatically generate Microsoft Exchange views”.
  4. Click OK.

Fixing the array_key_exists WordPress Warning/Error – The first argument should be either a string or an integer in

Warning: array_key_exists() [function.array-key-exists]: The first argument should be either a string or an integer in /your-sitepath/wp-includes/category-template.php on line 176

This problems stems from line 176 as stated above – some people have said that updating their wordpress theme worked, however, a simple change to line 176 seems to work perfectly.

Change line 176 from:

if(array_key_exists($category, $categories))


if(array_key_exists('$category', $categories))

Don’t see the difference? Just add single quotes around the first $category variable. Make sure they are not the curly single quotes.
