I am having the exact same problem. I tried to call my host site but they were not very helpful. I cannot login to my site nor can I even see the homepage to my site. it is
sarahkduke.com/unt
all that comes up is the 500 Internal Server Error
I am pretty sure it is messing up because I tried to add a widget or a plugin to make my login easier because I was having trouble logging in. Now I can’t even open my Dashboard to delete the plugins. What am I to do?
