Error Message on Firefox

I get the following errors when accessing from Firefox:
Warning: fopen(/usr/www/users/cornwaj/plugins/mobile/terawurfl/data/wurfl.log) [function.fopen]: failed to open stream: No such file or directory in /usr/www/users/cornwaj/plugins/mobile/terawurfl/TeraWurfl.php on line 457

Warning: fputs(): supplied argument is not a valid stream resource in /usr/www/users/cornwaj/plugins/mobile/terawurfl/TeraWurfl.php on line 458

Warning: fclose(): supplied argument is not a valid stream resource in /usr/www/users/cornwaj/plugins/mobile/terawurfl/TeraWurfl.php on line 459

How can i resolve it?

I was getting the same error message in Firefox today as well. ...just started using this plug-in today, I found a solution. Not sure if this is ideal/correct or not but the error message has gone away in Firefox and it's rendering the mobile version correctly on my phone.

There are four plug-ins in the Plug-in Manager. They are...

Mobile - Simple
Mobile - TeraWURFL
Mobile - Forever
Mobile - Domains


I turned them all off except for Mobile - Simple. It's working the way I want it to. Again, this might not be the solution you'd prefer because the other plug-ins are now deactivated.


EDIT: I just turned them all on, and left Mobile - TeraWURFL off. Firefox is not showing the error, and it's continuing to display the mobile template correctly on my phone.

The moment I activate Mobile - TeraWURFL, Firefox displays the error.

This issue will be fixed in 0.9.13. The easies way to solve it is make directory data in plugins/mobile/terawurfl.
