TOPIC: Invalid argument -subscription.php on line 38

Hi folks,
Suddenly, we're receiving this error in the CMC module on our site:

---

Warning: Invalid argument supplied for foreach() in .../administrator/components/com_cmc/helpers/subscription.php on line 38

You are already subscribed to our newsletter.

---

Any ideas as to what we're missing?

Looking forward to hearing from you.
Cheers!

PS. I just re-installed v3.0.1 ... this made no difference.

This is a warning and you can ignore it by setting error_reporting to off in joomla's global config.

I can't comment to why it is happening. 38 is a foreach that goes over all merge fields. Are users just subscribing to your list with just email and nothing more?

regards,
Daniel

Thanks Daniel.

I cleared the cache and the problem mysteriously disappeared.

Wow, so clearing cache is now the same as "did you try turning it off and on again"
