how to put web addresses?

Hello. I need to know how to put web addresses into a post. I wanted to publish the address of my gallery, but in doing so, a page appears with a message (Post denied New posts are limited by number of URLs it May Contain and checked if it does not Contain forbidden words.). Any help.
thanks
