Hmm, could you send me (denis@mobilejoomla.com) login/pass for backend access to your website?
oke
I've installed Mobile-Joomla.1.2.8.tar.gz and seems it works correctly (but I didn't install Remove Support Ads plugin and Elegance tempate). Please, install necessary addons (Elegance and remove-ads plugin), adjust settings and check that it works.
oke i try it
but I didn't install Remove Support Ads ? i this plugin I do not know ,I've installed the template but I think the weather is the same .You have every right to be able to do what you want, I always have a beckup not worry

I've checked in your profile that you have licenses for Elegance template and Remove Support Ads plugin (www.mobilejoomla.com/extension/advertising/remove-support-ads.html).
And I don't like to install something on customer's servers until it is the only way to fix the issue. Backup is good (and must to have) thing, but as I know nothing about your server I can easily do a mistake and break work of website, and restoring website from backup may take up to an hour depending on the size of database and filesystem.
many thanks for all your help i install ads en Elegance template .i will continue tomorrow
