I started my first self hosted WordPress blog and for optimizing my blog for SEO i changed the permalinks to /%category%/%postname%/
whereas the default permalink was http://techiezlounge.com/?p=123 which is not good option regarding SEO.
Everytime someone commented on my blog post it gave Error 404 though the comment got posted. I tried it myself and got the same response.
After some googling i found that it had to with permalinks and the solution was using .htacess , which i found quite confusing .
WordPress has lots of plugins and i found that if i used Dean Lee Permalink migration plugin my problem can be solved.
I installed the plugin and activated it in my admin dashboard.
Go to settings and then to permalink migration and do the necessary changes and update the file.
