Getting some weird error on webhost

Error message is
Catchable fatal error: Argument 1 passed to TeraWurfl::addTopLevelSettings() must be an array, null given, called in /home/a7600394/public_html/plugins/mobile/terawurfl/TeraWurfl.php on line 334 and defined in /home/a7600394/public_html/plugins/mobile/terawurfl/TeraWurfl.php on line 463
Please help how I can resolve it. Or I need to look through each file.

Most likely you have limited right on mysql5 server.
Choose mysql4 mode in 'Mobile-TeraWURFL' plugin settings.

This error can be caused if any file is missing during extraction.

I had the same problem, fixed it using mysql4 mode. Thanks
