Couldn't fetch mysqli Error

Hi Mobile Joomla,
I have been getting a lot of these errors in my error log and when I am loading pages on my site. What do these mean? How can they be fixed?.....

Warning: mysqli::real_escape_string() [mysqli.real-escape-string]: Couldn't fetch mysqli in /home/folmag/public_html/plugins/mobile/terawurfl/DatabaseConnectors/TeraWurflDatabase_MySQL4.php on line 395

Warning: mysqli::query() [mysqli.query]: Couldn't fetch mysqli in /home/folmag/public_html/plugins/mobile/terawurfl/DatabaseConnectors/TeraWurflDatabase_MySQL4.php on line 253

Thanks,

I don't know. I would reinstall MJ to reset TeraWURFLs database tables. Also, there was some recent fixes in TeraWURFL library, so wait for updates in MJ 0.9.13.
