many issues

1) As noted in your post in this thread , please let us know a URL we can test at
2) Let us know a URL for this as well. It sounds like either a) the Open Graph tags for that page are incorrect or b) Facebook isn't able to read the tags on that page for some reason.
3) Same issue as #2. We'll need to know why the Open Graph data is wrong or not being read.
4) This can be related to #2 and #3. We'd need to know how far you've made it through the Open Graph Action configuration . Let us know what steps you've completed and if it's posting for admins, but not regular users, or no one at all.

Thanks,

Thanks for the link. Hopefully, the below can help you resolve most of your issues.

1) Your site is loading the following CSS file:
/cache/gk/f8ede48e4fade906e1c06727f3e582be.css.php
That has the following style:That image is the Facebook image which is going behind everything. I'd recommend removing that style. Otherwise, add the following to your template's CSS which will fix the problem:
2) I just liked the page for "Time to Lace-Up for the CAAFA 6th Annual 5K Run/Walk". The popup showed the image, link and description for the page. On my wall, my comment, the title and an image showed as well. That all seems right to me. Can you test on that page, or let me know a specific page that isn't working?

3) Can you edit the module for Recommendations and set the "Domain" or "Href" parameter to just your domain. Right now, I think it's blank, which is likely causing problems.

4) Let me know if the above all gets going, and we can work on auto-posting content.

Thanks,
Alex
