I'm using Joomla 3.4.1 with CiviCRM 4.6.3 on a demo site as part of a re-design. I've used the CiviCRM profiles html snippet to create a Joomla signup module. See here for example.
It worked once - storing the name and email into CiviCRM and even re-directing to the proper page and giving a thank you message after it stored the data.
However, now when you hit "save" in the module, this time nothing is saved and it kicks you back to the front page. I've read the manual, searched the forums, and tried a bunch of stuff, but nothing works. What am I missing?
