Hello @Godfrey ,
When that Adobe Flash warning appears, does it say anything to the effect of "This Game Is Going Away Soon"? If so, it seems that's a newer issue that our engineers are looking into. To get around it, I'd recommend installing one of our landing page sign up forms as a hyperlink via the + Add a button function on your business page.
For full instructions:
Create a landing page in Constant Contact
Copy the link to the landing page
Go back to Facebook Business Page
Click on "+ Add a button" (or, if there is already a button, click it and choose Edit Button)
Under "Step 1: Which button do you want people to see?", choose "Contact you"
Choose Sign Up and click Next
Under "Step 2: Where would you like this button to send people?", choose Website
Paste in the form URL, click Save, then click Finish
With Facebook's many recent API and permissions changes, this will also likely be the most stable and consistent method of having your followers sign up as contacts. I've also submitted your case to the engineers regarding this issue. If and when they have an update for you, they'll notify you via email. At this time we don't have a hard ETA on a resolution. If you have any other questions, feel free to reach out.
