What urls are entered in Settings-> General? Did you change them after you installed WordPress?
I can´t access to my dashboard right now. Now that you mention it, that could have been the problem…
Do you know how I can fix it?
Thank you, Esmi
Can you access your website by FTP? (through your host)
Change the urls back to their original settings. See Changing_The_Site_URL.
I followed the steps from the link you gave me, Esmi, but now I can´t even login. My username and password don´t work anymore if I add those parameters in the config.php file.
Changing the site urls will have no effect on your username or password.
Finally, I was able to login in and access to my dashboard. So now, should I change the urls in the Settings?
@alenprei
I know I sent this info to you or someone about your site yesterday but I can’t find it. You have a commercial theme. WordPress.org cannot support commercial themes although occasionally someone will try. Your support can be found here

In addition your site was recently hacked. Possibly the repair or hack has left damage.
@esmi
Now my site seems to work properly, so thank you for your help.

I wasn´t aware I had to ask for support to graphpaperpress until now that you just mentioned it. You´re right, my site was hacked but I fixed it by deleting everything and reinstalling the lastest version of WordPress.
Thanks for those links, kmessinger. I had already looked at few of them when fixing my site. This reassures me….
