hey there,

Try go to your Joomla backend > Easydiscuss > setting > Layout > General > select Compile stylesheet to "Cache" > Click "test compile" (test admin, site, and module) > when all test completed > then go to Easydiscuss Dashboard > Click "Clear Cache" > Then clear Joomla cache, then the error message will not show out.

If that error message still appear, can you provide us with your Joomla backend and FTP access so we can help you check on this?

By the way, in the future you can just include your site's access once at http://stackideas.com/dashboard/site rather than needing to keep adding them in your replies
