syntax error Help

Hello !
I'm using Mobile Joomla for the first time, and i'm going kind of crazy because it doesn't work.

Here is my bug message :
Parse error: syntax error, unexpected '=', expecting '(' in /homez.309/catalogun/www/plugins/mobile/terawurfl.php on line 58

I'm working on Joomla ! 1.5.22 and I've downloaded the lastest version of Mobile Joomla.
I can go to the back end of my website but in the front end I have this bug message.
We actually host our website at ovh.
We have PHP 5, MySQL 5.1, and i'm running on Windows Seven 6.1.
I only tested the website on Iphone tester 3G/4G, and I'm using Mozilla or Chrome for internet.

The adress of the website is : www.perpignan-hotel-roussillon.fr

I have no idea of what's going wrong !
Maybe the file hasn't been well downloaded, maybe it's about the host, maybe i've done something wrong...

Can someone help a french girl to make Mobile Joomla work ? Please.
Thanks for reply.

Cécile.

Hi !
I'm still working on it, And after calling 3 times my host I've found how to configure PHP5 (in fact it's not available by default).

But now, I have another problem !

Bug message : Incorrect usage of Mobile Joomla.

the fact is that I don't need a subdomain to my website, so i didn't touch this.
I haven't assigned ton any mobile template. I don't know how to says to Mobile Joomla that by default it will always be on an iphone or pda or else.

For the moment the template use is JA_Purity and i didn't touch of the others templates

What is wrong ? Can someone explain to me how to configure Mobile Joomla well ?

"Incorrect usage of Mobile Joomla" means that one of mobile_*** templates is assigned to a menuitem.
