wp-admin cannot be viewed inside frames

Hi everybody,

I’ve a problem with the wp-admin area. In the past I was able to include the admin area of my wordpress installation inside frames. But a few weeks ago it was not working any more… (without a change in the system)…

When I try to open the admin page (within a frame) I see the login panel (as usal) but after login I get a white page. The login was succesful, I can open the admin page in another window and see the admin area (and do not need to log in again)…

I found this post but this didn’t work at my wordpress installation…

I tried the following steps:

• I updated to 3.4
• Renamed the plugin folder (and deactivated them prior)
• using the Twenty Eleven theme
• and of’course comment both lines with ‘send_frame_options_header’ in default-filters.php

Does anybody have an idea what else I can do?

Thanks in advance!
