V2 Activation prevents accessing wp admin

This site did have V1 previously installed, yes, when I uninstalled it I chose for it to delete all data for itself and it’s additional plugins.

This is a site that’s in development to replace our current site, so it’s not a test site specifically for the plugin, no. We have backups available though if we need them.

I have actually tried deactivating everything and changing the theme to the “Twenty Seventeen” theme by wordpress, and the plugin’s activation still broke the backend, so it doesn’t seem to be a conflict there. But yes, you can do that sort of thing when trying to figure it out.
Also, I have made sure that I’ve downloaded the most recent version of V2 (September 12th update).

Since you don’t have FTP access, I’ll check here often incase you need me to delete the plugin from the backend.

Thanks for the help!

I cannot grant that to you unless you make an account on our host’s website and become a collaborator on the project. I believe I would have to send a link to an email to do this, so if you are willing to make an account, let me know what email to send it to.
I can access the FTP, if you tell me where it’s located I can attach it to my reply.
