I have a wordpress installed in myblog.com then I install pligg myblog.com/pligg, but after I click submit new article (to test), it took me back to worpdress and show me the 404 not found page, help?


The best way, and for SEO purposes, is create a new sub-domain, eg: plig.yoursite.com - For your problem, it seem you have not instaled your pligg script inside the folder where is your domain. More info only if i can see it, please pm for me with your domain url. But first solution is better for all purposes.
