Try checking your site’s error logs for a more specific error message. Your hosts should be able to help you accessing your site’s error logs.
Okay I’ll contact the host. It usually takes a while for a response from them, would you recommend anything else for the time being?
Okay so I now have an error on my white screen, which says this:
Notice: wp_enqueue_script was called incorrectly. Scripts and styles should not be registered or enqueued until the wp_enqueue_scripts, admin_enqueue_scripts, or login_enqueue_scripts hooks. Please see Debugging in WordPress for more information. (This message was added in version 3.3.) in /home/content/57/9465357/html/wordpress/wp-includes/functions.php on line 3245

I’d bet whatever theme you are using is trying to enqueue scripts or styles directly onto the login page , which is a no-no. I only know that because I had to re-write a section of our plugin to abide by this new rule. Our users were getting similar errors.
Okay, thanks. I’ve deleted my current theme via FTP, but WordPress hasn’t reverted to the old theme, it still thinks I’m using my custom theme. I also disabled all plugins and the error messages have disappeared, so I’m left with a white screen. I also get a couple errors recurring in my error logs:

You seem to have at least 1 bad plugin. Try resetting the plugins folder by FTP or phpMyAdmin.
When I reset the plugins folder the error just returns. It seems the actual plugin causing the error is simple-intranet. I’m not really sure where to begin to fix the problem of my admin panel missing certain tabs or the front end whitescreen.
