I have the same problem, and it looks like I am following the instructions exactly. I would appreciate some help!
My wordpress website is http://www.sustainablesurf.org
So the App Domain setting on the FB App should be “sustainablesurf.org”?
This is what I have done, but I get the error above.
Let me know what to do. Thank you
I have got mine to work by adding both domain names in the app domains field without the www prefix. My website was originally setup with say, aaa.com.au. Subsequently we parked domain bbb.com.au on this website and this is the website we are referencing. Easier to park the domain than change the whole website setup with the hosting service.
I have a FB page for bbb and set the FB app to point to http://www.bbb.com.au in the site url. However it wouldn’t work with just bbb.com.au in the app domain field but when I added aaa.com.au to this field (i.e. it now reads bbb.com.au aaa.com.au) it worked.
Not sure if your situation is similar but it may help.
I got mine to work as well. Even though I was putting in the site URL without the www prefix, somehow FB wasn’t saving the value. Eventually it got saved, and now it works.
Nice app…
You have to make sure that your app is not in Sandbox mode as well. I got the same error and that was the solution for me.
Hi everyone,
I’ve updated the installation instructions to make configuring the plugin more clear. Filling in the app domains field is optional but always a good idea, especially if your site uses multiple subdomains or works on both the www- as the non-www version.
