Can no longer post blogs

When I go to post a blog I now get the following error:

Fatal error: Declaration of EasyBlogTableMediaManager::bind() must be compatible with that of JTableInterface::bind() in /home2/fidelxxx/public_html/administrator/components/com_easyblog/tables/mediamanager.php on line 46


any thoughts? I am using an older version of easy blog and also tried to update it. Unfortunately, it asks for a key which I do not have (I did not originally set up the easy blog on my site).

thanks
