Does anyone have any ideas?
BTW i’ve seen similar topics about blank pages. However I can see the login page fine – I enter my admin and password but it goes to a blank page with no source code.
Cleared cookies/cache – no luck.
turn on debugging.
put this in your wp-config.php:
define('WP_DEBUG',true);
see what get spits out.

I tried creating a new database and installing WP again. I was then able to get to the dashboard. When I made any changes however (posts, edit pages etc.) it would work but would just go to a blank page when you click ‘Save’ or ‘Publish’. The original problem has appeared again now though – after shutting down MAMP for a break and then starting it up again.
Hi,
I also can’t login. I don’t do any code modification at all and my blog has been working fine. Everything looks fine on the main page, http://www.trabal.org/socio.
It seems users are able to create accounts, login, and post, which they have done over the last few days. But when I click login from my two macs, I get these on the login page. And also I can’t login, my username/pw suddenly don’t work. Some users are also not able to log in.
Thanks for your help!

If you recently installed a new plugin then delete it – it might have a coding error in the form of a blank line at the top or bottom of the file. If not then maybe the problem is on line 11 of the fuctions.php file in your theme. Or maybe it’s another reason. Check the theme file first. Switch to a different theme and see if the problems goes away.
I’m having the same problem using WP 2.7.2 (I think) hosting on my machine with MAMP 1.7.2 on OS 10.5.6. I can find the login.php page, enter my information and submit it but that simply takes me to a blank page. Everything on the front-end is working fine. I’m using the Sandbox theme as a base for building a custom theme.
Any ideas???
After continued puzzling I went to the MAMP support forum and they suggested looking for white space in my wp-config. Sure enough, there was an extra line after the close of my php tag, and the same was true in my functions.php. Watch out for those white spaces!
