yoursite.com/wp-login.php will bring up the login dialog. (I just tried it on your site)
Something you might try just to gather some additional diagnostic information:
Go to yoursite.com/wp-login.php and try to log in. If it looks like you logged in, but you are taken to a blank page, then enter yoursite.com/wp-admin/options.php in the browser address bar to see if you can regain some back end navigation.
Sorry – should have provided my site in the first place! Thanks for trying that out. And I also should have clarified – I am able to log in, it’s just that when I do I’m taken to a blank dashboard. I tried your suggestions, but the blank page is persisting, unfortunately.
Do you have Yoasts Google plugin? If so delete it via FTP and then when your admin loads install new version. His one broke sites early this week. Otherwise check for spaces at start and end of your functions.php file.
yoursite.com/wp-admin/upgrade.php should show me a dialog similar to:
“No Update Required – Your WordPress database is already up-to-date!”
..but yours renders a blank page.
Conversely, yoursite.com/wp-admin/includes/upgrade.php should show me a blank page, however yours renders an error message:
Warning: require_once(ABSPATHwp-admin/includes/admin.php) [function.require-once]: failed to open stream: No such file or directory in /home/xxx/yoursite.com/wp-admin/includes/upgrade.php on line 16
Fatal error: require_once() [function.require]: Failed opening required ‘ABSPATHwp-admin/includes/admin.php’ (include_path=’.:/usr/local/lib/php:/usr/local/php5/lib/pear’) in /home/xxx/yoursite.com/wp-admin/includes/upgrade.php on line 16
yoursite.com/wp-admin/includes/update-core.php should probably show me a blank page, but in this case, yoursite.com/wp-admin/includes/update-core.php shows me this error message:
Fatal error: Call to undefined function add_action() in /home/xxx/yousite.com/wp-admin/includes/update-core.php on line 1151
I’m just guessing with a lot of this, but I think you could have some type of issue with missing or possibly damaged files in /wp-admin. Again, just guessing, mind you.
Sidenote: I also noticed that directories without index files aren’t protected against casual browsing. “Options -Indexes” in your .htaccess file will be something for later exploration.
(sorry about all the tracks I left in your access logs)
Edit your wp-config.php via ftp and set debug to true.
define( ‘WP_DEBUG’, true );
Load site and see if errors in admin page.
Also look at your error_log file also in root and see if errors.

Load site and see if errors in admin page.
The problem seems to be that the admin pages aren’t being displayed right now. Will ‘WP_DEBUG’, true still show an error? I’ve never tried that.
“About a week ago, I noticed that when I tried to get to my dashboard, nothing would display – just a blank, white page.”
Try what I suggested. I had white screen on Monday after Yoast plugin updated. What I suggested is how I found which plugin had killed my admin.
Thanks for the insight, everyone.
Clayton, thank you for letting me know about the index files! I’ll look into that after this issue is (hopefully) resolved.
Angus – I don’t have Yoast, and I’ve already set debug to true to see what errors are cropping up, but it doesn’t seem like the error has to do with this issue. Could be wrong, though! Here’s what I’m getting:
Notice: Undefined variable: args in /home/micyak/webcomicunderdogs.com/wp-content/themes/yamidoo/functions/theme/functions.php on line 65
This is what’s on line 65:
add_theme_support( ‘custom-background’, $args );
Does this sound like it might be a culprit?
The notice doesn’t seem likely that it would be an issue with your admin pages. If you like, you can try temporarily renaming just your active theme directory and let the default WordPress theme kick in and see if it makes any difference.
I wouldn’t think so either. Any empty spaces or lines after last character in functions.php was something I read to check when mine was an issue.
Hm…when I rename the active theme, the default theme does not kick in. The site displays a blank page, just like the dashboard.
Angus – I came across the same info, and have ruled out extra spaces in functions.php.
If this were one of my own sites, I would first take a complete backup – all files and the database – then try replacing just the /wp-admin directory with the content from a fresh download to see if that makes any difference. Your readme.html file indicates you are using version 4.0.1, so you want to make sure you download the correct version for the fresh file source.
If that makes no difference, I might try a manual replacement of all files and directories except /wp-content and wp-config.php
I cannot stress enough, the importance of making sure you first take a complete backup if you decide to attempt a manual reinstall/file replacement or upgrade. Some reference material: http://codex.wordpress.org/Updating_WordPress
