Can't access dashboard after configuring 'fix-multiple-redirects'

Hi, I am struggling with this. I was designing my site locally through MAMP and ftp’d it to the Host. They told me there were to many redirects when loading and to fix this. I installed the plugin ‘fix-multiple-redirects’ and activated this. Foolishly I configured it without really knowing what I was doing and when I refreshed my page this is what I got:

https://localhost:8888/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/frielms/

It should be just https://localhost:8888/frielms

I have tried disabling all plugins through php admin and this did not work. I have also deleted the ‘fix multiple direct’ folder. HAs anyone any idea how to solve this? Please and thank you
