I have a wordpress website at limerickjazzfestival.com
I always use the login page at /wp-login.php
And I am 100% certain that I am using the correct username and password, as it then takes me the the url http://www.limerickjazzfestival.com/wp-admin/
However, it just shows a blank screen. No information seems to be returning. Even different iterations like http://www.limerickjazzfestival.com/wp-admin/themes.php do not work.
I am very confused by this, and would appreciate any help on the subject. It is quite urgent.
I also have a Blacklist plugin installed, and believe I entered the wrong password/username at one stage yesterday, which may be relevant to this, but I doubt it.
