I am having problems with my newsletter subscription page. I didn't have this problem before so I suppose this is because I updated my site to version 2.3.4.
Here is the error I get:
[Warning] Invalid argument supplied for foreach() GET /ahonfound/mailing-list-subscription/ Line 262 in C:\wamp\www\ahonfound\newsletter\code\SubscribeForm.php
Similarly, I also get this error on the admin panel of the newsletter:
Any ideas? Thanks!
