I am sorry to heard that you have restored your EasyDiscuss with an old version . As we concern about the issue that hitting you, we suggest to you for temporarily copy your existing site to another test site, so we can upgrade the EasyDiscuss and troubleshoot this broken links issue.
I'm afraid we cannot do it right now. Cause there are serveral serious problems after I'd upgrade Easyblog and Easydiscuss. For I need Easyblog to show my blogs to some friends, I have no choice but make Easyblog working!
We really want to be helpful here. If you got time to create a test site where we can update the EasyDiscuss4 and troubleshoot the issue, kindly get back to us so we will assist you accordingly
