Bottom line, WordPress for Joomla is akin to forcing a square peg into a round hole. Even after you get it to work you know it was not meant to be. Imagine a bridge to an external program. Well this is like a bridge to an internal program.
There is a fantastic blog component built from the ground up for Joomla. So sorry I didn't investigate it before purchasing WordPress for Joomla.
I think most of the issues that were encountered with your situation were related to an unclear understanding of how Wordpress for Joomla works which is indicated by your comment "So sorry I didn't investigate it before purchasing WordPress for Joomla." Here at 'corePHP' we will answer any in-depth question about our products before purchase so you have a clear understanding of what you are purchasing. We also supply a workable demo site.
The product is working properly and we have spent many hours supporting the product for you. I would assert this level of support is greater than "barely average" but you are certainly entitled to your opinions.
As far as the plugins go, we do not state that all plugins work with Wordpress integration, though most do. The issue that you were having with a plugin was due to the fact that your Wordpress plugin would not pull images from JomSocial. While the plugin would display Gravatar icons as the plugin developer intended, it wouldn't display JomSocial images because no Wordpress developer would go out of their way to code for JomSocial, which is a Joomla component.
We thank you for your review.
