Hello Zoonini,
Thanks for the help. I did trun off the plugins and turned them on one by one. One plugin called ‘Redirect’ was causing this problem. Hence I removed it.
2) Now my second issue is that I have added one SEO post without any category. However wordpress assigns default category to the post.
The URL is http://www.aarisindia.com/blog/seo/seo-post.html
Instead of http://www.aarisindia.com/blog/seo-post.html
Best Regards
