Hey Chris,
I found this error:
Fatal error: Call to undefined method JDocumentRaw::addCustomTag
() in /home/deftadvisors/public_html/plugins/content/easyopengraph/easyopengraph.php on line <i>100<
/i>
I traced it and found that it is related to the Easy Open Graph plugin. I've disabled it and the autopost didn't give any error. However, there was still an issue with Facebook not showing the posts. I have to apply some fix in this file:
administrator\components\com_easyblog\includes\oauth\adapters\facebook\client.php
Afterwards, the autopost is working now as shown in the screenshot below.
If you want to use the Easy Open Graph plugin, I advice that you contact with the plugin developers and tell them about the error.
By the way, I can't access the K2technologies' backend. The path that you gave me doesn't work. If you can access the site, you can try disable the Open Graph plugin and replace the file attached in this post to the directory above.
