Hi,
I'm using Metatemplate Pro and I need some guidance about configuring it properly as I'm getting several error messages.  I've setup a rule to test a mobile template for all mobile devices accessing the website.  However I'm seeing the following messages:

On website home page after enabling a rule:

Warning: require_once(deviceDetection.php) [function.require-once]: failed to open stream: No such file or directory in

/public_html/plugins/metatemplate/extendedrules.php on line 460

Fatal error: require_once() [function.require]: Failed opening required 'deviceDetection.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /public_html/plugins/metatemplate/extendedrules.php on line 460


and in Metatemplate admin configuration page:

Warning: fopen(/public_html/administrator/components/com_metatemplate/geoip/GeoIP.dat) [function.fopen]: failed to open stream: Permission denied in /public_html/administrator/components/com_metatemplate/views/config/view.html.php on line 81

Warning: fopen(/public_html/administrator/components/com_metatemplate/geoip/GeoLiteCity.dat) [function.fopen]: failed to open stream: Permission denied in /public_html/administrator/components/com_metatemplate/views/config/view.html.php on line 81

Can you advise how to fix these?

Many thanks,

Al
