TOPIC: Get blank screen when trying to register

I am running 2.6.9c and have been having all sorts of problems with registrations.

When users try to register by clicking on the "Register" button, they get a blank screen in all browsers we've tried: FF, IE, Safari.... etc.

I had the problem before with the prior release and upgraded to 2.6.9c which fixed the problem.

Today, it stopped working again after we installed a new module. I disabled the module, no change in result.

This is a really big issue for us so any help we can get in resolving this mystery would really be appreciated.

Thanks for any help,

Well, it's working again happily, if mysteriously, since I didn't make any changes to any events, etc.

I wondered if it could be related to cookies and cached information that could have changed so I closed the browser and retried in IE and FF and it is working again.

Any ideas for what could be causing the behavior I and our users are seeing with this component?

I get the 404 error when trying to register your event clicking in the "register button" in the article. The button in the events list works properly.

Can you provide me an access information in PM, I will take a look
The 2.9 is working fine actually
