media manager not working?

Hi Stackideas,
i have been working with my client in a testing environment https://kuruvita.com.au/index.php/easyblog/dashboard/write - we have everything working as it should

I have just transferred the site to its home - https://kuruvita.com.au/index.php/easyblog/dashboard/write
im in the process of configuring the auto publishing apps etc.
I have noticed that the media manager no longer works - i cant seem to insert an image

any ideas how i might troubleshoot this?

thanks
