 * Hi,
 * I love toopher and use it for 2F for other apps. I would like to activate it 
   on my wordpress site too. However that will not work. I get this error:
 * Plugin could not be activated because it triggered a fatal error.
    Fatal error:
   Cannot redeclare class OAuthException in /home/<path_to_homedir>/public_html/
   wp-content/plugins/toopher-two-factor-security/lib/toopher-web/OAuth.php on line
   8
 * I already disabled all other plugins but still not able to activate.
 * Hope you can help me solve this.
 * Kind regards,
 * Mark

 * Hi Mark, sorry to hear you are having problems! I’m not able to replicate this
   with a clean WordPress 4.2.2 install with the Toopher-Wordpress 2.1 plugin. Do
   you have any themes installed? Are you self-hosting your blog, or using a cloud
   provider?
 * Thanks,
    Drew Shafer

 * Hi Drew,
 * Thanks for the reply. I am using a theme (can it be theme related?). I’m hosting
   my blog with an ISP.
 * Please let me know how I can help troubleshoot this. I would really like toopher
   integration with my blog.
 * Thanks!
