I'm assuming it was a typo, but in the example you posted above, the beginning of the URL is messed up:
{JFBCLike href=http:www//techjunkysolutions.net/web-design-maintenance/item/5-website-construction}
it should be http://www. not http:www// . Again, likely a typo, but if that's a cut and paste from your site, that's likely the problem.
As for testing, I went to the following page:
techjunkysolutions.net/index.php?option=...gory&id=103&Itemid=5
And the HTML being inserted into the page looks like:
<div class="jfbclike"><div class="fb-like" data-href="/web-design-maintenance/item/5-website-construction> </a>http://www.techjunkysolutions.net/index.php?option=com_faqbookpro&view=category&id=103&Itemid=5" data-show-faces="true" data-send="true"></div></div>
Not sure if that's the Like button you're working with, but something is definitely wrong there with the URL. Not sure what's screwing it up, but check that:
* There's no spaces between href=http (the href, =, and URL)
* The URL is full, as above
* There's nothing else in the tag that may be causing issues.
As for the actual URL, if you don't have any direct link to the 'actual' item that Facebook can link to and scan, then you'll have to use a different URL. That's something that you'd need to contact the FAQ Book Pro devs to implement as it's nice to be able to share a specific link to whatever it is you're displaying/sharing.
Hope that helps,
