I am totally new to blogging and wordpress, so please excuse me if my questions are not as clear as they should be.
I had just installed a new theme to my blog which is hosted by yahoo (because I thought it might be the most idiot-proof). While at the wp-admin page, I clicked on "Options" and at "WordPress address (URI):" which contained my blog's url, I tried to delete "/blog" which appeared behind the url. a dialogue box appeared advising me not to do so and I clicked on "ok" but the dialogue box kept appearing as I kept pressing "ok". that's the first problem - how do I prevent that?
then my browse, Firefox closed down. when I opened it again, i find that the blog no longer has any graphics and I cannot access my wordpress login page unless I insert "/blog" at the the url. when i get back to the "Options" page to try and reinsert what I had accidentally deleted, it says that I need to enable sending referrers, which I did by following the directions. But its not working. How can I normalise my blog, or reinsert "/blog" under Options - WordPress address (URI)?
I hope that makes sense. Many, many thanks in advance.
