This is the first post of this blog and I think I definitely need to write down what I have experienced while installing WordPress.
With the help of Softaculous, it took no time installing WordPress on my site. However, when I tried to login my newly installed wordpress, it simply failed. Regardless of what I typed in the username and password field, the browser just redirected me back to the login page after pressing the login button.
After searching the web for a while, I found that the problems seem to be a cookie issue. I followed the steps of deleting the cookies and caches for my browser However, the problem did not get solved.
Finally, I read the manual from WordPress Codex and learnt that Site Redirecting might cause issues. I immediately realized (remembered) that I have redirected all requests of http://kevinresol.com to http://www.kevinresol.com/. Further searching shows that in the wp_options table (of the WordPress database) there are two fields home and siteurl which controls the home page of my blog. Both of them pointed to the no-www version of my blog, I then changed them to the with-www version and the famous blog tool worked like a charm! Cheers!
