Do you have the content plugin installed/enabled? This plugin allows for stream generation, modifies the profile link, and allows commenting on articles without a comment extension! It basically does 3 things at once (technically 4 if you include the author box).

^ to what Josh posted above. Can you please check and get back to us?

Thanks, Josh,
I get a blank page after posting a Article, and no stream item is generated. :/
If we look to the plugin compability version, then looks like it does not support ES 1.3

The plugin works just fine on my end (ES 1.3.8 and Joomla 3.3.6). Give Mark your login/server details. The stacked team is trust worthy with this info (I'm very selective with who I give this info to).

Hello Steve,

Please provide us with the FTP access to your site

Enabled error reporting and now i get this:
Fatal error: Class 'ContentHelperRoute' not found in plugins/content/easysocial/easysocial.php on line 371

How to fix that?

It could be more than one error. Keep in mind that an issue like this is probably going to happen again down the road. So you need to decide for yourself if your willing to give site access to the stacked staff or apply a fix they give you (assuming they can without access). If they don't have access to your site and don't have the error on their end it will be much less likely that they will be able to resolve it.

Hello Steve,

Can you give this a try again?

Thank You Mark, it works now.

You are most welcome
