Not having access to dashboard

Hi,

The url is trackingwonder.com.

We’ve had issues with slow uploading times the past week or so and today the site was down.

Down as in the pages would come up totally white, no error on them – nothing.

I called godaddy they said all was fine and the site came back up. I can now see the site in chrome (but not safari).

in chrome, although i can see the site – i can not get trackingwonder.com/wp-admin to come up. it’s the white blank page.

what can be wrong and what can we do to resolve this issue?

Thanks!!
