Christopher,
Wanted to circle back on this question. The issue was definitely a silly one, and the fix we're implementing in the next release is below. In the /libraries/sourcecoast/profile.php file, in the scProfilesOnFetchData() function, there was the following line directly after fetching the field_map parameter:
if($socialFieldMap == "")
return;
That is being changed to:
if(empty($socialFieldMap))
return;
The update will check for an empty array or empty string, which is the desired behavior. At least silly mistakes have easy fixes.
Thanks again. Any input you have is welcome,
Alex
