Hi Marco-
Thanks for reaching out, I’m sorry to hear you can’t log into your account.
We here at BoldGrid don’t have any access to your website to assist with your WordPress account or password, but your web hosting provider may be able to help.
I checked out your website, and it looks like you are hosted by one of our Premium Support WordPress Hosting providers, InMotion Hosting.
InMotion has 24/7 telephone support available, check out their support page for information.
