Hi thank you for reaching out and thank you for using BoldGrid Post and Page Builder for WordPress!
I’m sorry to hear this has been an ongoing issue for you. If you have tried resetting the password using the ways we suggested your next step is to contact your Web Host and setup a support ticket. You may have to login to your cPanel and change the Password using their web tools. You could also be locked out of your site for more advanced reasons such as malware or a security threat. Either way they will be able to help you more with this. Your site is hosted by InMotionHosting, you can start a support ticket with them here.
I hope this helps!
