I have added the Facebook comments plugin to dynamic pages on my site, and I am attempting to set up administration of those plugins by adding the associated meta tags to their pages. My site uses the CMS dotnetnuke.
I went to the page's settings - under advanced - and added the appropriate meta tag information. However, upon saving, administration is not enabled on that page.
I ran the page through the wc3 validator, and the following error related to that meta tag was produced:
Error Line 11, Column 1926: there is no attribute "property"
…type="text/javascript"></script><meta property="fb:admins" content="76804243"/>

You have used the attribute named above in your document, but the document type you are using does not support that attribute for this element. This error is often caused by incorrect use of the "Strict" document type with a document that uses frames (e.g. you must use the "Transitional" document type to get the "target" attribute), or by using vendor proprietary extensions such as "marginheight" (this is usually fixed by using CSS to achieve the desired effect instead).
This error may also result if the element itself is not supported in the document type you are using, as an undefined element will have no supported attributes; in this case, see the element-undefined error message for further information.
How to fix: check the spelling and case of the element and attribute, (Remember XHTML is all lower-case) and/or check that they are both allowed in the chosen document type, and/or use CSS instead of this attribute. If you received this error when using the element to incorporate flash media in a Web page, see the FAQ item on valid flash.
Do I need to specify this attribute somehow in my DNN skin? Any ideas on a possible fix?
Thanks! Alex
There are several ways you can change the DocType for your site. Here's the entry from the DotNetNuke wiki that describes the options: http://www.dotnetnuke.com/Resources/Wiki/Page/Set-the-doctype-of-your-skin.aspx
