Can't access homepage of site

So I installed the plugin and I can’t access the homepage of my site… at all.
I keep getting redirected to the login page.

I have changed settings, deleted the plugin, altering the code and removing redirect referenced but nothing works.

Is there code somewhere that I can alter? I have tried reverting back to a saved copy of my site but it doesn’t work either.

Any help is appreciated.
