 * Hi,
 * The plugin activates fine, and I can open up the options and make changes, but
   I’m getting PHP errors and the plugin just doesn’t work.
 * WP: 2.6.1
    MyQSL: 5.0.41 PHP: 5.2.5
 * **Upon activation, here are the PHP errors:**
    [26-Aug-2008 10:11:13] PHP Warning:

 * UPDATE: I rolled back to WP 2.6, and that seems to have fixed the problem.

 * [@soniczen](https://wordpress.org/support/users/soniczen/) – I’m sorry that happened
   to you… I also recently upgraded to 2.6.1 without any issues… I believe the issue
   can be solved once upgrading to 2.6.1 by going to the YARPP settings page and
   re-entering your threshold value. Please let me know if that works for you.
