Hi Prashant,

Sorry for late reply to this,

You can 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.

It should fix this issues. If the issues still persists, can you provide us with your Joomla backend and FTP access so we can help you on this?
