I've been having a weird problem with the application when trying to use it in my site. I have a Multisite installation, and every subsite has a different Twitter account for auto-publishing (which is the addon I'm trying to use). Thing is, it worksion only one of them, on the first one I installed (which was a test subsite). On the other subsites, I keep getting this error:
Fatal error: Cannot redeclare class OAuthSignatureMethod_HMAC_SHA1 in (...)/wp-content/plugins/simple-twitter-connect/OAuth.php on line 82
Is it because I can't use the same app on the same site? Do I have to create several apps for every subsite? Does the callback URL setting make any difference?
Edit: I deleted it all, and created another app with the same twitter account, with a different callback URL (referencing the other subsite where I want to use the plugin). Same error happened. I'm going to try using a separate twitter account with another app and see what happens.
