kelcypar on "wp-admin showing up blank"

Hi there,

After entering in my credentials to the wp-admin login page, I am directed to a blank white page instead of the admin WP dashboard interface. No 404 error page or anything, but when I inspect the console it says "Failed to load resource: the server responded with a status of 404 (Not Found)"

I have contacted my host and they were not able to duplicate the error, however, I have tried (and failed) on 4 different computers and devices and 3 different browsers (Chrome, Safari, & Firefox.) I have also had a friend enter my credentials on their computer and they also were taken to a blank white page.

Any help?! This has never happened before and I need to make some important updates on my site.

Thank you in advance!
