Error message about TetaWURFL on installation

hello,

while installtion of mobilejoomla I received the following error message:

TeraWURFL is designed to work with MySQLi (MySQL improved) library.TeraWURFL will be disabled.

Nevertheless the component was installed completely. What does the error message mean? 

MobileJoomla has two plugins for device detection:
Mobile-Simple - really simple plugin that covers some most popular devices only,
Mobile-TeraWURFL - plugin based on TeraWURFL library that is able to determine almost all of existing mobile devices, but the library is based on PHP5 and MySQLi php extension (usually this extension is enabled on PHP5).

UPDATE:

mobile website is working now. One small problem: the link to the standard webpage leeds always to the mobile version. can this be fixed?

Thank you for your reply. I activated now simple plugin and the redirect to mobile.3ecke11er.de works. unfortunatelly links on www.3ecke11er.de do not work any more. they link only to the homepage

I got the same error. i cannot access the mobile website.. it gives an error. please  help.
