My Core DNN version is 04.08.02 and i'm trying to install forum version 04.04.03.  I have the website hosted on one of my hosting company's servers.

The forum module is listed as an available module but when i go to install it i get "Sys.WebForms.PageRequestManagerTimeoutException : The server request timed out."

Other modules have installed without error.

Has anyone any ideas what is causing this and/or what can be done to resolve it?

Thanks

Thanks for replying.  After some research i found that the install error relates to Ajax.  I disabled ajax on the host and the problem went away and the forum is was installed ok. 

Once installed I needed to run 'list' related sql fix as I had the following error going into the general settings page.

DotNetNuke.Services.Exceptions.ModuleLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.Modules.Forum.Settings.BindMemberNameTypes() at DotNetNuke.Modules.Forum.Settings.Page_Load(Object sender, EventArgs e)

But i continued to get the following error when trying to add a forum to a group.

DotNetNuke.Services.Exceptions.ModuleLoadException: Must specify valid information for parsing in the string. ---> System.ArgumentException: Must specify valid information for parsing in the string. at System.Enum.Parse(Type enumType, String value, Boolean ignoreCase) at DotNetNuke.Modules.Forum.ForumEdit.HandleForumBehavior() at DotNetNuke.Modules.Forum.ForumEdit.Page_Load(Object sender, EventArgs e)

It's another list related error because i have no list records for 'ForumBehavior'.  Perhaps this could be added to the sql fix?

Thanks

don't forget to restart the Application in the Hostsettings after you have running the scripts.
