No the problem's fixed now. I was able to edit other ppl's posts by clicking on my browser window where you type into on which website to go to and on one of the old visited topic links led me to the editing of another person's post. It's also only possible with editing the first post of every topic which is basically the guy who made the topic. I was found to be editing the manakinghts topic that's all but the problem fixed now so no need to worry.
