wp-admin doesn't load

We’re going to need a lot more information that that!

What version of WordPress are you currently using?
What theme?
Have you installed any plugins recently?
Made any other changes?
What’s the url of your site?
What happens when you try to login in?

I have the same problem. If this problem was caused by installing or updating a plugin, how can I revert the plug in if the admin panel is empty (white screen)?

I had the same thing happen when I had to add some code to one of my php files for a plugin to function correctly. I ended up with the same white screen and some error messages. I had my hosting through godaddy and was able to go into the file manager and remove the added code that way. Not sure who your hosting is through but I would suspect that they would have a way of accessing that specific file. Hope this helps.

Please post your own topic. Your problem – despite any similarity in symptoms – is likely to be completely different.
