When I try to edit the first page of my website, the message comes that I cannot because it's being edited by another person. I'm that other person. All other pages OK for me to edit. What do I do?
Browse to the .LCK of the page and delete the same. For example, if your first page is firstpage.html, then browse to http://YOURSITE.com/firstpage.html/lck. Choose the menu item, File--> Actions--> Delete Page.
This will delete the lock file and you can proceed to edit you first page.
Hope this sloves your problem.
