    This might be a conflict with another plugin using the same class "OAuthException"
    Would you be able to open the file on the plugin
    /wp/wp-content/plugins/yelp-reviews-ticker/lib/OAuth.php
    and find every time the word "OAuthException" (13 times) and change it to something else.
    for example "YelpOAuthException"
    That should fix it. please let me know if it does and I'll update the plugin.

    Thanks!
