Fatal error: Call to a member function is_main_query() on a non-object

Hello, I am currently having issues with my site(www.androidnigeria.com.ng). After I activate the DW Question and Answer plugin my site will display this error message:

Fatal error: Call to a member function is_main_query() on a non-object in /home/wp_eigbwi/androidnigeria.com.ng/wp-includes/query.php on line 764

Can someone tell what could possible with the plugin and my site?
Thanks.

I’ve just check and test on my local host and see that the DW Q&A working good on your theme. So, for this situation, please try to disable all your plug-in and active the DW Q&A, after that you can active one by one plug-in to see which can be conflict with the DW Q&A, if none of theme is conflict then please update or re-install your wordpress core. I’ll be much better if you can send me your FTP. Thanks
