 * Hi,
 * I just updated the plugin to 1.3.10 and I once put all the updated API info I
   got this error message after I pressed save
 * Fatal error: Class ‘OAuthSignatureMethod_HMAC_SHA1’ not found in /webroot/e/r/
   eraynai/elliraynai/www/wp-content/plugins/rotatingtweets/lib/wp_twitteroauth.
   php on line 65

 * As a first step, I’d suggest re-entering the data, but it sounds like it might
   be a clash with another installation of `/lib/OAuth.php`
 * Do you have any other Twitter plug-ins installed? Or other plug-ins (or a template)
   pulling data from other sites?

 * I tried re-entering the data, but it still doesn’t work.
 * I don’t have any other Twitter plug-ins installed. I might have data pulling 
   from another site, but not sure.

 * You could try changing
    `if(!class_exists('OAuthException')) require_once('OAuth.
   php');` to `require_once('OAuth.php');` in the `wp_twitteroauth.php` file, but
   be prepared to revert it – since it could well crash your site is `OAuth.php`
   has been installed by someone else!
 * Which other plug-ins do you have installed?

 * The [latest development version of the plug-in](http://downloads.wordpress.org/plugin/rotatingtweets.zip)
   may address this.
 * Can you try this and let me know?

 * It worked after I updated the plugin. Thank you very much Martin! I really appreciate
   your help.
 * Thanks again,
    Elli
