Mobile Version of Website doesn't work anymore

Hello,
I installed Mobile Joomla (Free version) yesterday it worked good , but then i tried something with the advanced settings and when you visited the Website via Smartphone you weren't redirected anymore. So this day i reinstalled Mobile Joomla and tried nothing with the Settings but it doesn't work anymore. What is my mistake?


My project uses a extra domain (in the following example www.myseconddomain.de) and i use a FRAME Redirection.
So that the domain: www.myseconddomain.de is redirected to www.webhostingdomain.de/myfolder (EXAMPLE)

Could you PM me actual url of your site?

Yes, of course! The url was sent per PM

Works well. I've opened domain with frame on Android, and it displays mobile version. Second domain (frameless) displays it correctly too.

How do you test?

It works only when i type in the www.webhostingdomain.de/myfolder when i use the Frame Redirection it shows me the normal Site what should i do?

I test it with my iPhone
