Internal error 500 when accessing wp-admin

[titanas]

There's seems to b a bug in 3.2 and 3.2.1 which prevents users from loging to wp-admin. The server returns internal error 500 when trying to access wp-admin but work fine when accessing /wp-admin/edit-comments.php or similar links.

No .htaccess and PHP memory size is pretty high (128MB). Running lighttpd and PHP 5.2

Installing WP 3.2.1 again didn't help.

Forums are getting more and more complains on this one.

Can you get to the wp-login.php page?

[titanas]

Nope. The only solution to this is edit-comments.php or edit.php etc

Were you running into this with previous versions of WP? Make sure you have all the correct modules you need for lighttpd: ​http://yourneighbours.de/writings/run-a-blazing-fast-website-on-lighttpd-with-wordpress/ Also, you can try upgrading to PHP5.3 if possible.

First things first:
What's the actual error message? If you're simply recieving a 500 response, chances are PHP/lighttpd is blocking the error from being displayed, check your error logs.

Have you disabled all your plugins and switched to the default theme, does the problem persist? (If you can't access those pages, simply rename the plugins and active theme's folder to revert)

[titanas]

Nope. The errors star occurring after WordPress 3.2.x installed. Everything was working fine before. Will try PHP 5.3.

The friendly message from Chrome says

Here are some suggestions:

browser based errors can be ignored

have you tried turning on php error display and disabling all plugins?

[titanas]

It seems the problem occurs with certain WordPress + plugin configurations. Unfortunately i can't disable all the plugins in my production blog. I'll try an update with the error logs

Feel free to reopen with the steps to reproduce on a clean install if there's still a problem.
