<p>I am trying to edit fields.  When I go to <code>Settings-&gt;Fields</code> and then click on a field, I get a message that reads:</p>

<pre><code>Internal Server Error

Craft\Model and its behaviors do not have a method or closure named "availableAssetSources".
</code></pre>

<p>Then I looked in the utility logs under server info, it reads:</p>

<pre><code>Level:  error
Category:   exception.Twig_Error_Runtime
Message:    exception 'CException' with message 'Craft\Model and its behaviors do not have a method or closure named "availableAssetSources".' in /home/christen/6989-CLG-Web/craft/app/framework/base/CComponent.php:266
</code></pre>

<p>I am including the code written on line 266, in case it helps:</p>

<pre><code>throw new CException(Yii::t('yii','{class} and its behaviors do not have a method or closure named "{name}".',
</code></pre>

<p>What does all of this mean and how can I fix it?</p>

<p>Thank you so much!</p>

I am trying to edit fields.  When I go to Settings->Fields and then click on a field, I get a message that reads:
Internal Server Error

Craft\Model and its behaviors do not have a method or closure named "availableAssetSources".

Then I looked in the utility logs under server info, it reads:

I am including the code written on line 266, in case it helps:
throw new CException(Yii::t('yii','{class} and its behaviors do not have a method or closure named "{name}".',

What does all of this mean and how can I fix it?
Thank you so much!

You're running [Craft 2.6+](https://craftcms.com/changelog#build2771) and you've got an older version of the [Redactor I](https://github.com/pixelandtonic/RedactorI) plugin installed that isn't Craft 2.6 compatible. If you [download the latest](https://github.com/pixelandtonic/RedactorI/archive/1.1.0.zip) version of the plugin and install it, the error will go away and Redactor I will work as usual.
