Log in = Blank white page

Hello Everyone,

I’ve been having a problem all week with our website and have not been able to edit anything. Monday WordPress was working just fine, but by the afternoon, this problem started suddenly where nothing appears when I try to load/edit any pages or posts in WP.
I enter my login information, press enter and the website accepts my information but does not load anything. When the login screen disappears to load the dashboard page, I just have a plain, white, blank page. Refreshing does nothing, I have tried this in both Safari and Firefox, several different user accounts that we have, different computers, everything I can think of and still nothing.
The website is still in tact and running properly, and when I am logged in to WP the WP toolbar still appears at the top of the website page, however still loads nothing but the same blank page when I click to edit anything.
I haven’t messed with any sort of coding ever, as I am not comfortable with it to be perfectly honest. I know very basic HTML and that’s really about it.
Can anyone offer a solution to me? I would very much appreciate any advice.
Thank you 🙂
