Settings Changed –> Trouble!

Well, i warn you that my english is NOT really god, and I’m really furious, so, I think it gets really worst.

That’s the thing: I’ve changed, in “setting”, the WP URL. It was like my-blog.com/blog, and I, for a unknown and stupid reason, have changed to this : my-blog.com.

Yeah.

So, I can’t acess my dashboard, and neither the login page, nothing.

Oh, and, as you can see, the blog can’t find the theme. I mean, you see? Me blog don’t have stylesheet anymore, for a unknown reason too.

And I don’t know if these can help you helping me, but I find out that:

-Acessing /blog or /index, is the same thing. I mean, the blog is there, in the same way.

-https://inspirazione.ip-urra.com/blog/wp-content/themes/ the page is there, actually, so, why i can’t acess my dashboard? WHY %&#@????

-I forgot what I suposed to say here.

-My english sucks, but I warn you(oh, what’s the past form of “warn”? I’m too furious and sad and…. AHHHHH PLEASE HELP ME -beatles, yeah)
