Online Event Registration (DT Register) - Session Data Lost

I'm currently developing a website with an online event registration system (using DT Register). There seems to be a problem with session data.

Click on any event to register. The problem comes after clicking next step, reviewing registration and then clicking back, nothing will happen after I click next step again. This problem also arises whenever user enters the wrong captcha code and needs to enter again.

We have opened a ticket with DT Register and this is what they had to say:

Hello. This is a problem stemming from your template. When turning on error reporting in Joomla, there are MANY php notices on the page coming from your template... then you see this Back / Next problem. However, I switched your template to the default Joomla template for a minute... no PHP warnings... and the Back / Next issue was not there.

So, definitely tied to the template itself. Seems maybe it is not keeping the session data. You need to check on the template side to see what it may be doing that would cause session data to be lost.

HELP?!?!!

Hi,

As I can see, the problem is that when you hit back button, the captcha will be changed, you have to input the correct code then it will allow you to click Next button again, if not the next button won't work.

The problem is actually after clicking "next step", there will only be a blank page. And if php errors are turned on there will be errors. Is there any issue with session data?

After inputting data and clicking Next, I got this http://easycaptures.com/fs/uploaded/403/7751358238.jpg

After clicking back and click Next button again, I got this http://easycaptures.com/fs/uploaded/403/5455466957.jpg

What's wrong?

Sorry for not posting the solution I found (thanks remp for PM-ing) so just for anyone wondering, this is how I solved this one:

At the Administration panel
Extensions > Template Manager > Click on active GavickPro template

And then > make sure "Mainbody Frontpage" is "Mainbody before component"

I think the default would be "Mainbody only"


The downside to this is that there will have to be some kind of article / module inside the layout.

Thanks for sharing that!

Cheers,
