wp-admin is a blank page

Hello I am a newbie on WordPress.

My website is dronedevotion.com and when trying to go to wp-admin I get a blank page. I think It has to do with the installation/activation of the plug in BridgeDD because before that it was all perfect. The only issue is that I have been managing wordpress online and I have not downloaded the desktop version.

Any clue on how to fix this? Thank you very much!
