If it is form 04.04.03 Version you using, check the first pinned thread in this forum.  Also it would be great to have some more informations from you about Forum and DNN version you are using.  Also it is important to know if it is a upgraded version frm 3.x Forum versions.

Hi,

I am also having the same problem on my DNN site; none of the Forum Threads are showing when I click on a forum. There definitely are some threads in there. The List script made no difference and I am now beginning to wonder whether there's something in my installation that is preventing the forum from working correctly. I am basically running DNN with a SQL login that only has EXECUTE permissions to all stored procedure, SELECT on views, and SELECT/EXECUTE on functions. No permissions are granted to any of the tables (the SQL login default schema is DBO but is not object owner; owner login was only used to install DNN ). This has already affected the search functionality; it doent work as a result of dynamic SQL in one of the stored procedures. But there is no dynamic SQL in Forum_Thread_GetByForum SP which I believe is the one I should be interested in for this case. DNN version is 4.7 and 4.9 (Separate installations) and Forum is version 04.04.03.
