Hello! I am Muhammad Waqas. My website is www.itworldblog.com. I am submitting my website on some directories such as www.livemorelink.com and some other related directories. But when I submit my website on it, it says that "URL is invalid or blocked: http://www.itworldblog.com". Due to this error I could not be submit my website on any web directory. Please guide me how do I solve this issue

Try adding slash after .com. Sometimes it does the trick.

Usually its easy to submit link, try to check the url and whats the error code that you get after submitting a link?
