The Constant Contact API plugin must be configured properly before using the For

I’m suddenly having a similar error — although my client’s CC credentials work fine, navigating to the Form Designer displayed two errors, ‘The Constant Contact API plugin must be configured properly before using the Form Generator.’ and ‘The Constant Contact Form Generator plugin requires WordPress 3.0 or greater. Sorry, folks!’

Re-factoring the function ccfg_compatibility_warning around line 55 of form-designer.php eliminated the second error. The first I traced to line 381 of functions.php, if(is_object($new_cc) && $new_cc->get_service_description()) {.

$new_cc->get_service_description()) always returns false, so the $cc object never gets created.

Any ideas? My client is limping along because I forced the object creation, which allows the public-facing and admin forms to display, but the widget-admin side is pretty thoroughly borked.

The site is running on IIS 7.5 with PHP 5.4.9. Plugin version is 2.3.12, WordPress is 3.5.1, though the same thing was happening on 3.5.0.

Your plugin is pretty impressive work, by the way.

2.4 didn’t fix my problem, but thanks. It’s looking like a Constant Contact problem after poking around more — passing good credentials to “api.constantcontact.com/…” won’t let me in, so (from the plugin’s perspective) requests return a null result. They haven’t been real helpful so far. I’ll post the resolution once I get it.

That was quick, Zack.
We got everything working a couple of hours ago. There was a lot going on so I’m not certain what the fix was:

1. I installed 2.4.0. I hacked on it a little bit but restored it to it’s original state after things started working and everything still worked. 2.4.0.1 works fine.

2. My client’s Constant Contact API login was broken — CC “did something” and I was able to login IF I pre-pended your API key followed by “%” to the username. The pre-pending appears to be irrelevant, now, but who knows?

3. The hosting provider fixed an issue in a wp-config file and another with cURL (which I suspect may have been the root cause of this misfortune).

So, I don’t believe your plugin was at fault in our case, though poking around in your code was fun.

I suggest the OP try to log in to “https://api.constantcontact.com/ws/customers/%5Busername%5D/lists” with her CC credentials and contact them if it fails.
