I've done a search here and it seems that the error is a missing yaf.core assemblt but I do have that installed and up to date. Here is my web.config file. Any ideas?

<add name="YafTaskModule" type="YAF.Core.YafTaskModule, YAF.Core" />

to

  <add name="YafTaskModule" type="YAF.Core.TaskModule, YAF.Core" />

Now it seems the only thing that is not working is the Admin and Host dropdown lists. Any ideas?

Regarding the menus check the browser console. Looks like the bootstrap js was not correctly loaded
