Yes, but I work on localhost and I put localhost/mysite and appears the error on the principal page. Then if I try to go to ohter sections of the page goes to the remote page.
thanks nintechnet, I followed the steps you put in the link that you have attached. When I uninstall the plugin what I see is that the ninjafirewall files continue to appear in the folder. The problem is still wrong
Should I delete them manually?
