 * The latest version has really slowed down page loading. Query Monitor reports
   the following issue:
 *     ```
       Trying to get property of non-object
       wp-content/plugins/dw-question-answer/inc/roles.php:267
       ```

 * Hi Kts915,
    We have tried to install a demo page with wordpress 3.9 and the latest
   version of DW Question Answer ( [http://prntscr.com/3mmnff ](http://prntscr.com/3mmnff)),
   we didn’t meet your problem, can you double check or try to re-install plugin.
   If you still meet this issue please go to designwall.com/question, submit a private
   question and give us an admin account for furtherchecking. Regards

 * Thanks for getting back to me!
 * This is on a localhost development site, so I can’t give you access. But the 
   problem is intermittent so, especially since you can’t reproduce it, I think 
   this is probably a plugin conflict. I have tried disabling all other plugins —
   and the most likely culprit seems to be Query Monitor itself!

 * Actually, I have finally managed to identify the culprit as [MainWP](http://wordpress.org/plugins/mainwp/).

 * Thanks, mainwp.
 * There aren’t many details: running DW Question & Answer and MainWP Dashboard 
   plugins on the same installation produces the above error in Query Monitor. I
   am running WP 3.9.1.
