I must admit to some confusion from your post, "I as the manager of my forum, want to edit a prior post, or delete or spam it."
First off you can only edit your own posts (no edit of any one elses posts) or delete them. Why you would wish to label your own post as Spam eludes me.
"for not making management settings of posts ABOVE the posts!" that is what I see on my Forums the functions are over the posts to the right side. You might want to post a screenshot if you have something different.
"I cannot re- edit or delete posts on my site because I cannot click on
the setttings they hi-light the posts words instead? Where I was
attempting to re edit a thread, I got that thread moved elsewhere and
then dumped by lefora? I did not dump it,," Once again, you can not edit other peoples posts. At the First post to a Topic the Admin actions drop box allows you to edit the name only of the Topic, Move the Topic to a different Category and Group, Sticky, Lock the Topic from further posting, Mark as Spam and/or Delete the entire Topic and all associated posts under it. (I suspect this may be what happened to your lost posts). Following posts only have the delete/spam action unless they are one of yours and than edit is also available.
Now in the Admin Panel you can setup Groups>with Categories under. You can edit the name of the Groups. You can Edit the name of the Categories. You can move either of these and even delete so long as any Topics are moved to a existing Category. You do not delete Topics within the Control panel that is done with the control above the first post to a Topic in the regular view of Forum.
BTW when doing a edit of your own posts you need to move the cursor about with the space bar before it will allow you to make the edit it is a known bug. (This is sentence above was a edit added after I posted originally)
Now if this does not help perhaps you can give a explanation of what steps you took and whether you used the Admin actions in the Control Panel or those within a Topic/post. Any screenshots of the problems would be good to post to help troubleshoot.
