I went to that page and resaved it (even though all were checked) and after that it worked. Front end moderation permissions appeared to be imported from vBulletin just fine, so I don't need to change anything there.
I've been told there is supposed to be a sidepanel on the reports area with buttons to close reports, etc. Why would this not be displaying? Any ideas? I do have the Widget framework addon installed and am using a custom side bar, but if I need to set something to enable the moderation side bar, please let me know.
There are no options, the report centre sidebar is just there.
As you're using Widget Framework, I suspect you are using the "All" position in the Clear Sidebar widget and possibly other widgets too. Don't use the "All" position as it carries out the action everywhere, including in the Report Centre, hence making the Report Centre sidebar disappear. You should use named templates instead eg forum_list. If you need for further guidance on using template names and hooks,you can post about these in the Widget Framework discussion thread.
