xthreads.php plugin file leaves forum in blank page

[Alan11]

I first uploaded this and was able to visit it in the admin CP and activate it.  Upon attempting to set up a prefix, it just refreshed the page upon submission, like what happens with the board messages and awards plugins. I can edit the last two via phpMyAdmin, but I cannot update it via the admin CP. The blank page problem occurred after xThreads. By renaming xthreads.php to 1xthreads.php, I can stop the blank page. I tried disabling other plugins individually to see if any resulted in a fix and that did not work. I am using the latest of all plugins and the myBB board. I checked if it was any problems between connecting to the database, but there was nothing wrong.
