I read about some other guy having this same problem a couple of weeks ago, so I thought I'd put up my quick solution. The latest version of WP (3.8 onwards, I think) has some compatibility issues with a few plugins. This can sometimes cause the WP Admin Dashboard to be blank. Here's how I fixed it: Go to phpmyadmin. Find the wp_options table. Look for the "active_plugins" option. Edit it, and cut all the contents of the big textbox into Notepad. Or just delete them. It's no big deal. We are remotely disabling our plugins. Next, try access your WP Dashboard. It should be showing some content now. Go to Plugins > Installed Plugins. Activate them one by one, until you find the culprit. For me, the problem plugin was W3 Total Cache, which I could simply update while it was disabled, and then activate, along with the rest. Problem solved!
