I installed this plug-in, but when I tried to activate it, I got the message:
Plugin could not be activated because it triggered a fatal error.
Fatal error: Cannot redeclare class OAuthException in /home/ubcecess/public_html/wp-content/plugins/widget-embed-lastest-tweets/twitteroauth/OAuth.php on line 8
I recently had the same probléme and it was because there was already a other Twitter plugin which used the same authentication library that “Widget embed latest Tweets” plugin. I deactivated the old plugin first and it work.
Do you have an other plugin who connect to Twitter ? Can you deactivate it ?
