Please Help! Enabled use of legacy widgets now website crashed

I installed page builder today and none of the widgets were available for the pre-build pages. I decided to manually download the widgets-bundle and transfer them over to my server. From there I still couldn’t access them after rebooting so after reading elsewhere that you need to enable legacy widgets through the page builder settings.

After that my website instantly died and I have no way of even accessing the wp-admin page.

I tried deleting all of the widgets bundle files and restarting to no avail. I have a feeling i’m going to have to edit one of the .php files to disable the use of legacy widgets but I don’t know where to start.

Any help would be greatly appreciated.

thanks in advance
