Accounts not showing up

I’m using suitecrm ondemand version 7.12.5 and for some reason, I cannot open accounts, I first imported them and that’s when the issue first started then when I deleted them and began manually inputting I got the same thing. It just shows a blank screen.
Has anyone had a similar issue? I’ve only been working on this for a week (and I am brand new at this), but it worked just fine when I first put in accounts.

Where is you installation hosted?
