 * Hey there,
 * when I try to activate the plugin WP throws me an error:
 *     ```wp-block-code
       Fatal error: Uncaught Error: Call to undefined method Redux::disable_demo() in /var/www/xxx.info/html/wp-content/plugins/worth-the-read/worth-the-read.php:22 Stack trace: #0 /var/www/xxx.info/html/wp-admin/includes/plugin.php(2314): include_once() #1 /var/www/xxx.info/html/wp-admin/plugins.php(192): plugin_sandbox_scrape() #2 {main} thrown in /var/www/xxx.info/html/wp-content/plugins/worth-the-read/worth-the-read.php on line 22
       ```
   
 * Any hints on that?

 * Sorry about that, fixed the bug and released 1.13.1. Please update the plugin
   and re-activate it. Let me know if you have any further issues. Thanks!

 * I get this with 1.13.2 and can’t activate due to fatal error:

 * That error is actually coming from the Redux Options framework that the plugin
   uses. This is a third-party options framework which other plugins use as well.
   It is possible there is a conflict. Please try disabling your other plugins and
   let me know if WTR begins working correctly.
