I've got what seems to be a pretty serious problem.
After entering my username and password for the admin area of my site, I'm met with a blank browser window and the admin area won't load.
I've tried on Safari and Firefox and on mac and pc, but I just see a blank browser after entering my username and password.
I've also tried to reset the password. When I click to request a new password, I again get a blank browser, but the reset request is sent to my email account.
Any ideas please?
