<p>That error indicates that Craft is missing some files (or they are corrupted) in its <code>craft/app</code> folder.  You can download a fresh copy of Craft from <a href="https://craftcms.com" rel="nofollow">https://craftcms.com</a> and replace your existing <code>craft/app</code> folder with the new one and that should resolve it.</p>

<p>I'm getting white blank page when trying to access my website and Craft login page. I haven't updated the website for few months. So I assume no files has been changed.</p>

<p>I checked with the hosting provider, and they say everything is okay on their part. </p>

<p>So I turned on the Dev Mode. And it came back with this error :
<code>Fatal error: Class 'Craft\HttpRequestService' not found in /home/alpw7814/craft/app/framework/YiiBase.php on line 213</code></p>

<p>What could possibly cause this? Is there anything I need to check?
Thank you in advance.</p>

Sounds like some of your core files are missing (or corrupted). Have you tried to re-download Craft; replacing the `/craft/app` folder with a fresh copy?

I'm getting white blank page when trying to access my website and Craft login page. I haven't updated the website for few months. So I assume no files has been changed.

I checked with the hosting provider, and they say everything is okay on their part.

So I turned on the Dev Mode. And it came back with this error :
`Fatal error: Class 'Craft\HttpRequestService' not found in /home/alpw7814/craft/app/framework/YiiBase.php on line 213`

What could possibly cause this? Is there anything I need to check?
Thank you in advance.

That error indicates that Craft is missing some files (or they are corrupted) in its `craft/app` folder. You can download a fresh copy of Craft from <https://craftcms.com> and replace your existing `craft/app` folder with the new one and that should resolve it.
